[dxvk] Introduce transient memory flag for staging buffers
...
Potentially reduces fragmentation by putting short-lived staging buffers
and sysmem resources created by the application into different memory pools.

[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 memory heap budget

Allows more fine-grained control of memory allocations for specific
heaps. For now, target 80% for device-local heaps on UMA devices.

[dxvk] Prefer VRAM allocation over dedicated sysmem allocation
...
May in some cases improve performance when under memory pressure:
If a dedicated allocation is preferred, but the alloaction fails,
try to allocate memory from an already allocated chunk instead
of falling back to system memory right away.

[dxvk] Remove dxvk.allowMemoryOvercommit option

The default behaviour is now to allow overallocation by default,
which makes sense especially when VK_EXT_memory_priority is used.
Does not seem to affect Nvidia drivers.

[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.

Optimized command submission
...
Command submission now does not synchronize with the device every single
time. Instead, the command list and the fence that was created for it are
added to a queue. A separate thread will then wait for the execution to
complete and return the command list to the device.
