py/objstr: Protect against creating bytes(n) with n negative.
...
Prior to this patch uPy (on a 32-bit arch) would have severe issues when
calling bytes(-1): such a call would call vstr_init_len(vstr, -1) which
would then +1 on the len and call vstr_init(vstr, 0), which would then
round this up and allocate a small amount of memory for the vstr. The
bytes constructor would then attempt to zero out all this memory, thinking
it had allocated 2^32-1 bytes.

py/objstr: Make empty bytes object have a null-terminating byte.
...
Because a lot of string processing functions assume there is a null
terminating byte, so they can work in an efficient way.
Fixes issue #3334 .

Add basic implementation of bytes type, piggybacking on str.
...
This reuses as much str implementation as possible, from this we
can make them more separate as needed.
