virgl: resources without any binding can be cached

Browse Source 
Certain games create and destroy lots of resources without binding them.
This can take quite a bit of time and even create unneeded
synchronization. However, we know that if a resource was never bound to
anything, it can be cached. This change does that.

Counting the number of uncached allocation with a tabletop simulator trace:
Before: 2967 uncached allocations over the replay
After: 24 uncached allocations over the replay
