drm/xe: Remove dependency on intel_lrc_reg.h

Create regs/xe_lrc_layout.h file with all the offsets used by the xe
driver. Eventually the xe driver may use a different way to define them
since it doesn't supported below gen12.

v2: Rename file to intel_lrc_layout.h since it's not really about
    registers (Matt Roper)
