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
lock-free by creating a slab allocator which allows us to lookup a
pointer directly from a 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.

If separate transitions of the depth and stencil plane occur in the
same array of barriers, they will be consolidated into one Vulkan
layout transition. This can only be supported for combinations of
depth read and depth write states, or identical states.

Fixes an assertion when compiling shaders with more than four
clip or cull distances. Output arrays are arrays of scalars,
so shifting the write mask is not very meaningful.

There appears to be a complete implementation of RS 1.1 already,
so enable this feature.

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.
