bpo-44525: Split calls into PRECALL and CALL (GH-30011)

* Add 3 new opcodes for calls: PRECALL_METHOD, CALL_NO_KW, CALL_KW.

* Update specialization to handle new CALL opcodes.

* Specialize call to method descriptors.

* Remove old CALL opcodes: CALL_FUNCTION, CALL_METHOD, CALL_METHOD_KW, CALL_FUNCTION_KW.

+Replace the four call bytecode instructions which one pre-call instruction
+and two call instructions.
+
+Removes ``CALL_FUNCTION``, ``CALL_FUNCTION_KW``, ``CALL_METHOD`` and
+``CALL_METHOD_KW``.
+
+Adds ``CALL_NO_KW`` and ``CALL_KW`` call instructions, and
+``PRECALL_METHOD`` prefix for pairing with ``LOAD_METHOD``.

 (Note this code is from an early 3.11 alpha, the NOP may well have be removed before release).
 
 If an instruction raises an exception then its offset is used to find the target to jump to.
-For example, the CALL_FUNCTION at offset 6, falls into the range 2 to 8.
+For example, the CALL_NO_KW at offset 6, falls into the range 2 to 8.
 So, if g() raises an exception, then control jumps to offset 14.
