[Intel-gfx] [PATCH 2/6] drm/i915/gt: Move SFC lock bits to intel_engine_regs.h

These SFC registers were defined in an usual way, taking an engine as a
parameter rather than an engine MMIO base offset. Let's adjust them to
match the style used by other per-engine registers and move them to
intel_engine_regs.h.
While doing this move, we can drop GEN12_HCP_SFC_FORCED_LOCK completely;
it was intended for use in an early version of a hardware workaround,
but was no longer necessary by the time the workaround was finalized.
It is not used anywhere in the driver.
