drm/xe: Remove dependency on intel_engine_regs.h

Create regs/xe_engine_regs.h file with all the registers and bit
definitions used by the xe driver. Eventually the registers may be
defined in a different way and since xe doesn't supported below gen12,
the number of registers touched is much smaller, so create a new header.

The definitions themselves are direct copy from the
gt/intel_engine_regs.h file, just sorting the registers by address.
Cleaning those up and adhering to a common coding style is left for
later.
