rp2: micropython.const return value is not int

[mishal]

The return value of micropython.const for rp2 port (I did not not check other ports) is wrong:

def const(expr) -> int:

Micropython allows to declare also string, tuple,... if built with enabled flags MICROPY_COMP_CONST and MICROPY_COMP_CONST_TUPLE, enabled by default in rp2 build (by MICROPY_CONFIG_ROM_LEVEL_EXTRA_FEATURES flag)

from micropython import const

_INT = const(123)
_STR = const("str")
_BYTES = const(b"bytes")
_TUPLE = const((_INT, _STR, _BYTES))
_TUPLE2 = const((None, False, True, ..., (), _TUPLE))

See the test in micropython source:

Thanks for the report,

I'll update it to `Union[int,str,bytes,Tuple] That way it will not be wrong, even if it doesn't get the details of a specific port/board/build
