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
