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.

Readback (GPU write, CPU read) should use different CPU page
properties compared to upload (write-back vs write-combined).
A future commit will start to respect these PB usage flags.

If we have a context, make sure any work on it's done before
reading from the render target. There may even be pending
MSAA resolves that haven't been submitted yet.

Always use the experimental shader models feature, which allows
unsigned DXIL to be used, so we don't need a libdxil for WSL.

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.

It's hooked up in all the pipe wrapper drivers, and all the
frontends except a couple places in glx/xlib.
This enables a more efficient path for drivers which use
swrast's Present, but hardware rendering (e.g. d3d12, zink).
