Add mip map bias for virtual texture sampling.
Respects the existing r.MiipMapLodBias CVar.
Also add residency tracking for each virtual texture physical pool.
If the pool has been created from a config with the bEnableResidencyMipMapBias flag set then a mip map lod bias is applied to bring the pool back within budget.
The residency mip map lod bias is applied globally (combined with the global mip map lod bias).
In future it could be good to apply the mip map lod bias per physical pool, but this will require tracking all physical pool combinations for each page table.
Physical pool residency tracking can be shown on screen with r.vt.residency.show CVar.
