GH-118095: Use broader specializations of CALL in tier 1, for better tier 2 support of calls. (GH-118322)

* Add CALL_PY_GENERAL, CALL_BOUND_METHOD_GENERAL and call CALL_NON_PY_GENERAL specializations.

* Remove CALL_PY_WITH_DEFAULTS specialization

* Use CALL_NON_PY_GENERAL in more cases when otherwise failing to specialize
