Make intel_pxp_is_active a global check and implicitly find
the PXP-owning-GT.
As per prior two patches, callers of this function shall now
pass in i915 since PXP is a global GPU feature. Make
intel_pxp_is_active implicitly find the right gt so it's transparent
for global view callers (like display or gem-exec).
However we also need to expose the per-gt variation of this for internal
pxp files to use (like what intel_pxp_is_active was prior) so also expose
a new intel_gtpxp_is_active function for replacement.
