There's not really a reason to directly map textures. Doing so
requires the texture to be allocated in system RAM instead of
video RAM, which means all GPU access to it would be needlessly slow.
Notably, the one texture type that was allocated this way is the
display target texture for the software driver path. Instead, use
pipe_transfer_map to be able to copy the texture to system RAM.

For non-CPU-accessible pipe resource types (DEFAULT/IMMUTABLE),
allocate non-CPU-accessible buffers directly from the cache_bufmgr.
Update the d3d12_bo creation to handle nonmappable buffers.
For CPU-write-only (DYNAMIC/STREAM), use the upload slab_bufmgr.
Update this slab manager to use CPU_WRITE | GPU_READ PB usage.
For CPU-read-write (STAGING), use the readback_slab_bufmgr.

Currently all buffers are allocated as mappable, but a future
commit will change that so that some buffers can be allocated
directly in non-CPU-accessible memory for improved performance.
Note that the returned pointer must be appropriately offset from
a 64-byte-aligned base pointer, so if offsets are used, the data
will be read/written to an offset region in the staging buffer.

We've been inconsistent between IID_PPV_ARGS,
__uuidof(var), and __uuidof(type). Since Linux doesn't
support the latter of these, they need to be changed.
While we're at it, switch all __uuidof to the more terse
IIV_PPV_ARGS option.

MSVC has an extension for getting IIDs (GUIDs) from types. Other
compilers can support this extension when targeting Windows, but
don't support it when targeting Linux. Instead, winadapter.h
defines __uuidof(var) to uuidof<decltype(var)>. Then dxguids.h
provides inline specialized definitions for the known D3D types.

This does 2 things for us:
1. Allows us to compile-time depend on any features from new headers,
instead of having to conditionally compile based on Windows SDK version.
2. Allows us to reference d3d12.h when compiling for non-Windows.

Some D3D enums have invalid values (e.g. NONE) in the enum,
so default: makes sense to catch invalid values in those cases.

This is the combination of a lot of commits from our development branch,
containing code from several authors.
