gobject_gdb.py: support gsignal fastpath and detect more marshallers

Browse Source 
- Commit f02ec2f2de added a gsignal fastpath where g_closure_invoke_va()
is directly called from g_signal_emit_valist() skipping signal_emit_unlocked_R()
altogether which it's the function used by gobject_gdb.py to detect
signal emission.

So we update gobject_gdb.py to also detect signals which use this
g_closure_invoke_va() fastpath.

- We also update the existent code to detect marshallers to also
include these:

surface_event_marshaller()
gdk_surface_event_marshallerv()
g_type_class_meta_marshal()
g_type_class_meta_marshalv()

This allow us that for signal emissions which use those marshallers
to keep showing the signal handler frame just after the
<emit signal blabla> line.
