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

* 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).

Use two or three bytecodes to implement most calls.
Calls without named arguments are implemented as a sequence of two
instructions: ``PRECALL; CALL``. Calls with named arguments are implemented
as a sequence of three instructions: ``PRECALL; KW_NAMES; CALL``. There are
two different ``PRECALL`` instructions: ``PRECALL_FUNTION`` and
``PRECALL_METHOD``. The latter pairs with ``LOAD_METHOD``.
This partition into pre-call and call allows better specialization, and thus
better performance ultimately.
There is no change in semantics.
