glib-private.c: Add private API to override invalid parameter handler

Browse Source 
...if supported, as in the previous commit.  We will eventually use
these private API to override the invalid parameter handler as needed
in the other parts of GLib and the tests.

We also now use _set_thread_local_invalid_parameter_handler()
instead of just _set_invalid_parameter_handler() to be safer, if
that is available.

This can be expanded upon in the future if we desire to use a stricter
or more customized invalid parameter handler.
