Rework CALL_FUNCTION* opcodes

Browse source 
Issue #27213: Rework CALL_FUNCTION* opcodes to produce shorter and more
efficient bytecode:

* CALL_FUNCTION now only accepts position arguments
* CALL_FUNCTION_KW accepts position arguments and keyword arguments, but keys
  of keyword arguments are packed into a constant tuple.
* CALL_FUNCTION_EX is the most generic, it expects a tuple and a dict for
  positional and keyword arguments.

CALL_FUNCTION_VAR and CALL_FUNCTION_VAR_KW opcodes have been removed.

2 tests of test_traceback are currently broken: skip test, the issue #28050 was
created to track the issue.

Patch by Demur Rumed, design by Serhiy Storchaka, reviewed by Serhiy Storchaka
and Victor Stinner.
