iris: Implement query_memory_info() on discrete cards

Browse Source 
This has been stubbed since 2019, but wasn't advertised or implemented.

Neither kernel offers us any interface for tracking evictions, but we
can at least report the size of various heaps.

Fixes various SPECviewperf subtests on Alchemist.
