[dxvk] Rework allocation logic for large resources
...
This may reduce internal fragmentation with very large resources.
We previously changed behaviour to not do this in order to reduce memory
pressure in the average case, however by trying to suballocate from existing
chunks and falling back to a dedicated allocation on failure, rather than
allocating a new chunk, we can mostly avoid that situation.

[dxvk] Be smarter about which chunks to free

Freeing all empty chunks immediately may cause issues if an app constantly
allocates and frees a small number of resources that don't fit into any
existing chunk, so try to keep one around. Aggressively free everything
under memory pressure if necessary.

[dxvk] Introduce concept of priorities to device-local memory allocations
...
The priority defines the importance of any given allocation being
resident in device-local memory rather than system memory, with
values between 0 (low) and 1 (high).
Suballocations will only work on chunks with the requested priority.
This ensures that high-priority allocations are reserved solely for
high-priority resources, and that high-priority resources will be
allocated from a high-priority memory chunk.
