bpo-46329: Split calls into precall and call instructions. (GH-30855)

Browse source 
* Add PRECALL_FUNCTION opcode.

* Move 'call shape' varaibles into struct.

* Replace CALL_NO_KW and CALL_KW with KW_NAMES and CALL instructions.

* Specialize for builtin methods taking using the METH_FASTCALL | METH_KEYWORDS protocol.

* Allow kwnames for specialized calls to builtin types.

* Specialize calls to tuple(arg) and str(arg).
