[issue29318] Optimize _PyFunction_FastCallDict() for **kwargs

[INADA Naoki]

INADA Naoki added the comment:

Since mutating kw dict shouldn't affect caller's dict, caller and callee can't share the dict.

One possible optimization is using PyDict_Copy() to copy the dict.
It can reduce number of hash() calls.
