bpo-46329: Streamline calling sequence a bit. (GH-31465)

* Move handling of bound-methods to PRECALL.

* Remove call_shape.postcall_shrink

* Remove call_shape.callable

* Remove call_shape.callable. Change CALL oparg to match PRECALL oparg.

* Move KW_NAMES before PRECALL.

* Update opcode docs in dis.rst

``argc`` is the total of the positional and named arguments, excluding
``self`` when a ``NULL`` is not present.
``CALL`` pops all arguments and the callable object off the stack,
calls the callable object with those arguments, and pushes the return value
returned by the callable object.
