Remove practically unused parameter

The `cached` out parameter of `php_com_load_typelib_via_cache()` was
meant to signal whether a particular typelib actually has been cached.
This is not really relevant, though, for the imagined purposes, and
since the parameter is no longer really used, we removed it altohether.
