Find the depth of cache objects matching cache depth and type.
Return the depth of the topology level that contains cache objects whose attributes match
cachetype. This function intends to disambiguate the case where hwloc_get_type_depth() returns
If no cache level matches,
HWLOC_TYPE_DEPTH_UNKNOWN is returned.
HWLOC_OBJ_CACHE_UNIFIED, the depth of the unique matching unified cache level is returned.
HWLOC_OBJ_CACHE_INSTRUCTION, either a matching cache, or a unified cache is returned.
-1, it is ignored and multiple levels may match. The function returns either the depth of a uniquely matching level or
