Subject: Pass CFX_*StringCs to FX_HashCode_GETA and _GETW hash functions.

Too many calls were of the form fn(x.c_str(), x.GetLength())
which is an anti-pattern given the StringC classes which tie
these together.

There are a few places where explicit CFX_*StringCs are
constructed, but this can be avoided by changing the args
to these functions in the same manner.

Removed String_ from name of functions since it added
little value. Also removed default argument.
