5f8f32f917 extmod/modnetwork: Use a type protocol to implement NIC functions.
This was previously implemented by adding additional members to the
mp_obj_type_t defined for each NIC, which is difficult to do cleanly with
the new object type slots mechanism. The way this works is also not
supported on GCC 8.x and below.

Instead replace it with the type protocol, which is a much simpler way of
achieving the same thing.

This affects the WizNet (in non-LWIP mode) and Nina NIC drivers.

This work was funded through GitHub Sponsors.

d6d8722558 extmod: Make extmod.mk self-contained.
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.

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

a52cd5b07d py/obj: Add accessors for type slots and use everywhere.
This is a no-op, but sets the stage for changing the mp_obj_type_t
representation.

e8355eb163 py/obj: Add "full" and "empty" non-variable-length mp_obj_type_t.
This will always have the maximum/minimum size of a mp_obj_type_t
representation and can be used as a member in other structs.

8308f9c977 extmod/network_wiznet5k: Use the configured DNS address if available.
Instead of the default 8.8.8.8.  The change was suggested by @omogenot.

af6d2845fa extmod/network_wiznet5k: Extract SPI transfer function dynamically.
Instead of using the fixed machine_spi_type entity to get the SPI transfer
function, this transfer function is now extracted dynamically from the type
of the SPI object.

This allows the SPI object used to communicate with the WIZNET5K hardware
to be SoftSPI or hardware SPI, or anything that has the SPI protocol (at
the C level).

f000ac9e82 extmod/network_wiznet5k: Rearrange the function wiznet5k_poll().
To have just one exit and a more compact flag test.  This is just a style
change without impact to the functionality.

999b66d531 extmod/network_wiznet5k: Schedule clearing of interrupt flags.
Avoiding conflicts between the IRQ and an active transfers.  Before this
change the device could lock up in heavy traffic situations.

Fix found and code supplied by @omogenot.

73699a846c extmod/network_wiznet5k: Deinit the NIC before (re-)initialisation.
If nic.active(True) is called several times in a row, the device may lock
up.  Even if that is bad coding practice, calling wiznet5k_deinit() in
wiznet5k_init() prevents the lock.

be2beab71a extmod/network_wiznet5k: Drop obsolete argument count check.
Drop an obsolete and wrong argument check, which prevented specifying a pin
for the interrupt signal.  The proper checks are now done further down in
the code.

21b3a396de extmod/network_wiznet5k: Add Wiznet Ethernet network interface.
Originally based on both stm32/network_wiznet5k and stm32/modnwwiznet5k.

If MICROPY_PY_LWIP is enabled it uses the lwIP TCP stack in MicroPython,
communicating with the Wiznet controller in MACRAW mode.  In this mode it
supports using the INTN pin from Wiznet controller to receive data from an
interrupt trigger.

If lwIP is not enabled, it runs in modnetwork/socket mode providing an
interface to the TCP stack running on the Wiznet controller chip.  In this
mode it includes some updates by @irinakim12 from #8021, most notably
bringing in DHCP support.

Supports defining hardware pins in board config or dynamically set at
runtime.  Sets a default MAC address in the random namespace from board
unique-id.
