drm/xe/pf: Move SR-IOV GT debugfs files to new tree

Browse Source 
Instead of expanding GT debugfs directories with large number of
SR-IOV files, as those are replicated per each SR-IOV function,
move them to our new debugfs tree, organized by the function.

But to avoid breaking IGT tests that use current layout, provide
symlinks which could be removed once transition period is over,
or we can we can leave them for convenience.
