drm/xe/uapi: Expose the L3 bank mask
The L3 bank mask is already generated and stored internally with
the rest of the GT topology. In user space, the compute runtime
now needs this information to be added to the device properties
therefore the topology mask query is extended to provide a new
mask which represents the L3 banks enabled on the GT.
The changes in the compute runtime are ready and approved, see
link below.
v2: Rewrite commit message and add a link to the compute
runtime PR (Francois Dugast)
