drm/xe: Move struct xe_vram_region to a dedicated header

Let's move the xe_vram_region structure to a new header dedicated to VRAM
to improve modularity and avoid unnecessary dependencies when only
VRAM-related structures are needed.

v2: Fix build if CONFIG_DRM_XE_DEVMEM_MIRROR is enabled
v3: Fix build if CONFIG_DRM_XE_DISPLAY is enabled
v4: Move helper to get tile dpagemap to xe_svm.c
