d3d12: Sets all SRV descriptors as data-static 

As Mesa d3d12 is currently implemented, all resource data is static
at the time a SRV or CBV is created.  Therefore, it makes sense for all
descriptors to use the DESCRIPTORS_STATIC_KEEPING_BUFFER_BOUNDS_CHECKS
flag.  Use of this flag broadens debug validation and allows some
optimizations in the underlying driver.
