[issue27213] Rework CALL_FUNCTION* opcodes

[Demur Rumed]

Demur Rumed added the comment:

Since the most common use of CALL_FUNCTION_EX is..

def f(*x,*kw):
    other_func(*x, **kw)

I've added some code to BUILD_MAP_UNPACK_WITH_CALL & BUILD_TUPLE_UNPACK to not allocate a new object if called with oparg of 1 & TOP() is correct type
