drm/i915/fbc: Moved fence related code away from intel_fbc
As a preparation for Xe move HW fence details away from intel_fbc code.
Add new functions to check support for legacy fencing and fence id and use
these in fbc code. Xe doesn't support legacy fencing.
v2: Fix intel_gt_support_legacy_fencing macro
