PEP-498 allows for conversion specifiers like !r and !s to convert the
expression declared in braces to be passed through repr() and str()
respectively.
This updates the logic that detects the end of the expression to also stop
when it sees "![rs]" that is either at the end of the f-string or before
the ":" indicating the start of the format specifier. The "![rs]" is now
retained in the format string, whereas previously it stayed on the end
of the expression leading to a syntax error.
Previously: `f"{x!y:z}"` --> `"{:z}".format(x!y)`
Now: `f"{x!y:z}"` --> `"{!y:z}".format(x)`
Note that "!a" is not supported by `str.format` as MicroPython has no
`ascii()`, but now this will raise the correct error.

Starting with 2757acf6, the `top` variable in `nlr_jump()` in
`nlraarch64.c` was assigned to register `x19` by the compiler. However,
the assembly code writes over that register with
ldp x19, x20, [%0, #32]
since `%0` is now `x19`. This causes the next line
ldp lr, x9, [%0, #16]
to load the wrong values.
To fix the issue, we move the value of the `top` variable from an unknown
register to a known register at the beginning of the asm code then only use
known/hard-coded registers after that.

Previously sys.path could be modified by append/pop or slice assignment.
This allows `sys.path = [...]`, which can be simpler in many cases, but
also improves CPython compatibility.
It also allows sys.path to be set to a tuple which means that you can
clear sys.path (e.g. temporarily) with no allocations.
This also makes sys.path (and sys.argv for consistency) able to be disabled

Prior to this commit, importing a module that exists but has a syntax error
or some other problem that happens at import time would result in a
potentially-incomplete module object getting added to sys.modules.
Subsequent imports would use that object, resulting in confusing error
messages that hide the root cause of the problem.
This commit fixes that issue by removing the failed module from sys.modules
using the new NLR callback mechanism.
Note that it is still important to add the module to sys.modules while the
import is happening so that we can support circular imports just like
CPython does.

NLR buffers are usually quite large (use lots of C stack) and expensive to
push and pop. Some of the time they are only needed to perform clean up if
an exception happens, and then they re-raise the exception.
This commit allows optimizing that scenario by introducing a linked-list of
NLR callbacks that are called automatically when an exception is raised.
They are essentially a light-weight NLR handler that can implement a
"finally" block, i.e. clean-up when an exception is raised, or (by passing
`true` to nlr_pop_jump_callback) when execution leaves the scope.

To use this:
- Create a built-in module, and add the module object as a member of the
parent module's globals dict.
- The submodule can set its `__name__` to either `QSTR_foo_dot_bar` or
`QSTR_bar`. The former requires using qstrdefs(port).h to make the qstr.
Because `bar` is a member of `foo`'s globals, it is possible to write
`import foo` and then immediately use `foo.bar` without importing it
explicitly. This means that if `bar` has an `__init__`, it will not be
called in this situation, and for that reason, sub-modules should not have
`__init__` methods. If this is required, then all initalisation for
sub-modules should be done by the top-level module's (i.e. `foo`'s)
`__init__` method.

This makes it so that sub-packages are resolved relative to their parent's
`__path__`, rather than re-resolving each parent's filesystem path.
The previous behavior was that `import foo.bar` would first re-search
`sys.path` for `foo`, then use the resulting path to find `bar`.
For already-loaded and u-prefixed modules, because we no longer need to
build the path from level to level, we no longer unnecessarily search
the filesystem. This should improve startup time.
Explicitly makes the resolving process clear:
- Loaded modules are returned immediately without touching the filesystem.
- Exact-match of builtins are also returned immediately.
- Then the filesystem search happens.
- If that fails, then the weak-link handling is applied.
This maintains the existing behavior: if a user writes `import time` they
will get time.py if it exits, otherwise the built-in utime. Whereas `import
utime` will always return the built-in.
This also fixes a regression from a7fa18c203
where we search the filesystem for built-ins. It is now only possible to
override u-prefixed builtins. This will remove a lot of filesystem stats
at startup, as micropython-specific modules (e.g. `pyb`) will no longer
attempt to look at the filesystem.
Added several improvements to the comments and some minor renaming and
refactoring to make it clearer how the import mechanism works. Overall

If sys.path is enabled, but empty, this will now no longer search the

This also provides an alternative mechanism to the u-prefix to force an

Changes in this commit:
- Add MICROPY_GC_HOOK_LOOP to gc_info() and gc_alloc(). Both of these can
be long running (many milliseconds) which is too long to be blocking in
some applications.
- Pass loop variable to MICROPY_GC_HOOK_LOOP(i) macro so that implementers
can use it, e.g. to improve performance by only calling a function every
X number of iterations.
- Drop outer call to MICROPY_GC_HOOK_LOOP in gc_mark_subtree().
When a tuple is the condition of an if statement, it's only possible to
optimise that tuple away when it is a constant tuple (ie all its elements
are constants), because if it's not constant then the elements must be
evaluated in case they have side effects (even though the resulting tuple
will always be "true").
The code before this change handled the empty tuple OK (because it doesn't
need to be evaluated), but it discarded non-empty tuples without evaluating
them, which is incorrect behaviour (as show by the updated test).
This optimisation is anyway rarely applied because it's not common Python
coding practice to write things like `if (): ...` and `if (1, 2): ...`, so
removing this optimisation completely won't affect much code, if any.
Furthermore, when MICROPY_COMP_CONST_TUPLE is enabled, constant tuples are
already optimised by the parser, so expression with constant tuples like
`if (): ...` and `if (1, 2): ...` will continue to be optimised properly
(and so when this option is enabled the code that's deleted in this commit
is actually unreachable when the if condition is a constant tuple).

When := is used in a comprehension the target variable is bound to the
parent scope, so it's either a global or a nonlocal. Prior to this commit
that was handled by simply using the parent scope's id_info for the
target variable. That's completely wrong because it uses the slot number
for the parent's Python stack to store the variable, rather than the slot
number for the comprehension. This will in most cases lead to incorrect
behaviour or memory faults.
This commit fixes the scoping of the target variable by explicitly
declaring it a global or nonlocal, depending on whether the parent is the
global scope or not. Then the id_info of the comprehension can be used to
access the target variable. This fixes a lot of cases of using := in a
comprehension.

This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.
Make all extmod variables (src, flags, etc) private to extmod.mk.
Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.
Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

Removes the need for the port to add anything to OBJS or SRC_QSTR.
Also makes it possible for user-C-modules to differentiate between code
that should be processed for QSTR vs other files (e.g. helpers and
libraries).

Only intended to be used on Unix and other "OS" ports. Matches CPython.
This should give the absolute path to the executing binary.
