Damien George 079f3e5e5b py/parse: Allow all constant objects to be used in "X = const(o)". 
Now that constant tuples are supported in the parser, eg (1, True, "str"),
it's a small step to allow anything that is a constant to be used with the
pattern:

    from micropython import const

    X = const(obj)

This commit makes the required changes to allow the following types of
constants:

    from micropython import const

    _INT = const(123)
    _FLOAT = const(1.2)
    _COMPLEX = const(3.4j)
    _STR = const("str")
    _BYTES = const(b"bytes")
    _TUPLE = const((_INT, _STR, _BYTES))
    _TUPLE2 = const((None, False, True, ..., (), _TUPLE))

Prior to this, only integers could be used in const(...).
