Make intel_pxp_is_enabled a global check and implicitly find the
PXP-owning-GT.
PXP feature support is a device-config flag. In preparation for MTL
PXP control-context shall reside on of the two GT's. That said,
update intel_pxp_is_enabled to take in i915 as its input and internally
find the right gt to check if PXP is enabled so its transparent to
callers of this functions.
However we also need to expose the per-gt variation of this internal
pxp files to use (like what intel_pxp_enabled was prior) so also expose
a new intel_gtpxp_is_enabled function for replacement.
