Force release of pages from the LRU virtual texture page pool if we are requesting a locked page.
This reduces case where new virtual texture producer can't map the root page.
Also only update adaptive VT indirection texture when the allocated VT root page is mapped.

Fix invalidation of Adaptive Virtual Textures.
We need to gather all of the Allocated VTs in the AVT and invalidate the pagaes associated with their individual producers.

Flush virtual textures pending delete before allocating new virtual textures if we are about to exceed virtual texture space limit.
Avoids hitting space limit in some cases where pending queue is otherwise slow to flush (such as during cook).

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.

- This should be much faster than previous code which attempted to map all mip levels
- Need to ensure at least lowest resolution mip is mapped, in order to avoid rendering frames with garbage data mapped
- Add warning for AllocatedVTs that never manage to complete this mappings

- Instead, keep VT cached for a few frames after they are deleted, this way they can be re-used if they're deleted/recreated due to state changes
- This should solve the problem of material changes causing pages to become unmapped for a few frames

- Check partially allocated block for fit, don't need to start with a completely free block for allocations
- Try to use the lowest possible vAddress for new allocations, this reduces the texture area covered by allocations
- Page table is no longer required to be square power-2 texture, instead allow it to grow organically as allocated area increases
- Allocator starts with maximum-sized block and tracks allocated area, no longer needs special logic to 'grow'
- Rectangular allocated VTs now mip based on min-size rather than max-size, relaxes alignment requirements and allows better packing
