drm/xe: Allow VRAM BO allocations aligned to 64K

Browse Source 
While today we are getting VRAM allocations aligned to 64K as the
XE_VRAM_FLAGS_NEED64K flag could be set, we shouldn't only rely on
that flag and we should also allow caller to specify required 64K
alignment explicitly.  Define new XE_BO_NEEDS_64K flag for that.
