To support concurrent readers on multiple command queues/devices, Dawn
must support importing via wait multiple fences and also export a signal
fence. The previous implementation of using a single fence for waiting
and signaling doesn't work for concurrent reads across queues.
This CL adds support for specifying multiple wait fences for
ExternalImageDXGI via a BeginAccess method that's meant to replace
ProduceTexture. There's also an EndAccess method that returns a signal
fence for the client.
For performance reasons, we use the same fence as the signal fence that
the Device uses internally, and record its value on the texture after
ExecuteCommandLists. Therefore, the CL also makes the Device's internal
fence a shared fence so that we can export it to the client.
This CL also expands the ConcurrentExternalImageReadAccess test so that
it tests fence synchronization across multiple devices. A number of test
helpers also now take an optional device parameter so that we can use
pixel value expectations with secondary devices.

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."

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.

DXGI external images can now be imported with both fence and texture
shared handles. Fence wait and signal values can be specified for
ProduceTexture. Keyed mutex functionality is kept as is with no change.
The D3D12 resource wrapping tests now run in both keyed mutex and fence
modes.

This CL updates the clang format files to have a single shared format
between Dawn and Tint. The major changes are tabs are 4 spaces, lines
are 100 columns and namespaces are not indented.

This CL changes several includes which were using the system include
syntax to the local syntax. This causes GN check to verify that the
headers are specified correctly in the dependencies.
Two missing dependencies are added to the BUILD.gn file for the
Dawn tests.
