drm/xe: Add MI_COPY_MEM_MEM GPU instruction definitions
MI_COPY_MEM_MEM GPU instructions are used to copy ctx timestamp from a
LRC registers to another location at the beginning of every jobs
execution. Add MI_COPY_MEM_MEM GPU instruction definitions.
v2:
- Include MI_COPY_MEM_MEM based on instruction order (Michal)
- Fix tabs/spaces issue (Michal)
- Use macro for DW definition (Michal)
