[PATCH] drm/xe: derive mem copy capability from graphics version

[Nitin Gote <nitin.r.gote@intel.com>]

Drop .has_mem_copy_instr from the platform descriptors and compute
it in xe_info_init() once handle_gmdid() populates graphics_verx100.
Early init was running with graphics_verx100==0, so the old placement
silently disabled MEM_COPY on every GMDID platform. Centralizing the
GRAPHICS_VER(xe) >= 20 || platform == XE_PVC check keeps Xe2+/PVC enabled
and removes redundant per-platform plumbing for future Xe platforms.

Bspec: 57561

Fixes: 1e12dbae9d72 ("drm/xe/migrate: support MEM_COPY instruction")
