Signaling a fence in Dawn without waiting can cause a race between Dawn
and Chromium over who signals the fence. Since D3D12 fences are allowed
to be rewound this can cause future waits to hang indefinitely if Dawn
loses the race and signals a lower value than what Chromium expects.
The signal without wait case happens when Dawn submits no command lists
e.g. when CopyExternalImageToTexture uses a zero-sized dimension. This
is the reason for the test failures in https://crrev.com/c/3700811 e.g.
https://ci.chromium.org/ui/p/chromium/builders/try/dawn-win10-x64-deps-rel/24617/overview
To fix the race, it's sufficient to wait before signaling if not already
waited which is what this CL does. This CL also makes the fence stay
alive until pending signals are done - this wasn't the root cause of the
hang described above, but it's still a good idea for robustness, and
also recommended based on discussion around past Chromium XR fence use.

- For the depth stencil textures with RenderAttachment usage, they will
always be cleared with ClearDepthStencilView() instead of copy, then
the following copies will be correct.

D3D12 objects can have implicit dependencies on device resources that
are not captured by holding ComPtrs:
"Direct3D 12 uses COM-style reference counting only for the lifetimes of
interfaces (by using the weak reference model of Direct3D tied to the
lifetime of the device). All resource and description memory lifetimes
are the sole responsibly of the app to maintain for the proper duration,
and are not reference counted. Direct3D 11 uses reference counting to
manage the lifetimes of interface dependencies as well."
Source: https://docs.microsoft.com/en-us/windows/win32/direct3d12/important-changes-from-directx-11-to-directx-12
ExternalImageDXGI can outlive the device it was created on e.g. the D3D
shared image backing holds on to the ExternalImageDXGI for its lifetime.
ExternalImageDXGI destructor can invoke code that depends on D3D12
resources that might have already been destroyed. In particular, this
shows up as ComPtr::Release for ID3D12Fence crashing mysteriously, and
is also speculated as the cause for a racy invalid function pointer
dereference in crbug.com/1338470.
This CL makes the D3D12 backend device destroy the ExternalImageDXGI's
resources on device destruction making it effectively a weak pointer.
This unblocks landing https://crrev.com/c/3700811 and hopefully fixes
crbug.com/1338470 as well.
This CL also deprecates unnecessary WGPUDevice param to ProduceTexture,
and adds an IsValid() method so that the shared image can check it and
decide to recreate the ExternalImageDXGI if needed.

In Mach engine we compile Dawn's d3d12 backend using Zig as a C/C++
compiler, effectively clang with MinGW windows headers. Unfortunately,
this `static constexpr` fails to compile:
```
error: constexpr variable 'kD3D12PromotableReadOnlyStates' must be initialized by a constant expression
```
As kangz previously noted, the reason appears to be because `D3D12_RESOURCE_STATE_COPY_SOURCE`
is not `constexpr` [in MinGW headers](1de9cc347d/mingw-w64-headers/include/winnt.h (L682)).
The thought process is that making this just `const` is fine because
constant propagation would make it a constant anyway.
If we're comfortable merging this, it'd be one less change we have to
maintain on our side - and probably no impact otherwise. On the other
hand, I understand the most-correct fix would be in MinGW headers
themselves. I'd love to land this change, but it's no big deal if you
prefer not.
