Greatly reduce VA allocations we have to make and makes returned VA more
sensible, and better matches returned VAs we see on native drivers.
D3D12 usage flags for buffers seem generic enough that there
is no obvious benefit to place smaller VkBuffers on top of
VkDeviceMemory.
Ideally, physical_buffer_address is used here, but this works as a
good fallback if that path is added later.
With this patch and previous VA optimization, I'm observing a 2.0-2.5%
FPS uplift on SOTTR when CPU bound.

The GPU VA allocator was allocating memory in a way where dereferencing
GPU VA required a lock + bsearch to find the right VA range.
Rather than going this route, we turn the common case into O(1) and
lockless by creating a slab allocator which allows us to lookup a ptr
directly from GPU VA with (VA - Base) / PageSize.
The number of allocations in the fast path must be limited since we
cannot trivially grow the allocator while remaining lock-free for
dereferences.

By setting this flag, command pools cannot efficiently pool allocations.
This flag should be set to 0 so only the VkCommandPool may be reset.
This matches D3D12 API.

D3D12 command allocators are intended to recycle memory across resets,
so we should do the same thing in vkd3d.

It is possible to map a resource, but not disclose the VA to caller.
This is used for WriteToSubresource.

Shadow of the Tomb Raider overwrites descriptors while they are being
copied in another thread. This patch makes reads and writes atomic for
CBV, SRV, UAV, and sampler descriptors, but not RTV and DSV, for which
copying is not implemented.
Benchmark total frames vs mutex count (the single mutex was locked
only once for copying):
1 mutex: 6480 6489 6503
8 mutexes: 6691 6693 6661
16 mutexes: 6665 6682 6703

The "allocations" array is filled with unused entries when D3D12 buffers
are destroyed. The majority of entries might be unused after running for
a while. Remove the entry when VA is freed in order to prevent
accumulation of unused entries. This makes destroying D3D12 buffers more
expensive.
