samd51: Enable functionality to support CPython stdlib

Browse source 
This enables various things in order to support the CPython standard library.

MICROPY_PY_BUILTINS_NOTIMPLEMENTED:
Support NotImplemented for easy conversion of stdlib.
It doesn't do fallbacks though, only raises TypeError.

MICROPY_PY_COLLECTIONS_ORDEREDDICT:
collections.OrderedDict

MICROPY_PY_FUNCTION_ATTRS:
Support function.__name__ for use as key in the function attribute workaround.

MICROPY_PY_IO:
uio module: BytesIO, FileIO, StringIO, TextIOWrapper
Also add 'io' alias.

MICROPY_PY_REVERSE_SPECIAL_METHODS:
Support the __r*__ special methods.

MICROPY_PY_SYS_EXC_INFO:
sys.exc_info() used by unittest when collecting exceptions.

MICROPY_CPYTHON_COMPAT:
Some of the things it adds:

>>> object.__init__
<function>
>>> object.__new__
<function>
>>> object.__class__
<class 'type'>
>>> object().__class__
<class 'object'>
>>> object.__name__
'object'

>>> 'Hello'.encode()
b'Hello'
>>> b'Hello'.decode()
'Hello'

Named tuple field names from string:
namedtuple('Point', 'x y')
