Unused aspects of depth-stencil attachments that are tagged as read-only
used to leak that read-only state to backends, even if the validation
made it seems like they always match (they only need to match if the
texture has both aspects). This confused backends like Vulkan which
checked for depthReadOnly || stencilReadOnly to choose between code
paths.
Instead reyify the depthStencilAttachement descriptor in the frontend to
protect against garbage values being passed for aspects that aren't
present in the texture.
Adds a regression test, with the caveat that a failure is only shown by
having the VVL output and error in stderr due to an unrelated issue.

- Cleanup is necessary because otherwise encoded render commands may be

can then trigger an assert in ~Device::Cache because the commands can

Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members. This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.
Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).

This CL modifies the way adapter creating devices, adds `shader-f16`
feature, and deprecates the `dawn-shader-float16` feature which is no
longer used.
Details:
1. Parse the toggles chained with device descriptor in
`adapter::CreateDeviceInternal`, which are then used to validate
features requirement within `CreateDeviceInternal` and passed to device
constructor as initializer.
2. When creating device, validate features requirement in
`CreateDeviceInternal` with toggles known, make sure to fail the device
creation if a required feature is not supported by adapter or is guarded
by certain toggles which were not enabled/disabled. Feature ShaderF16
and ChromiumExperimentalDp4a are validated in this way. Unittest is
added to check creating devices with toggles-guarded features required.
3. Add `shader-f16` feature, which allow `using f16;` in WGSL code.
End-to-end tests are added to test a trival f16 WGSL shader could be
used if and only if the device has `shader-f16` feature.
4. Deprecate the `dawn-shader-float16` feature, which will be completely
removed after cleaning up Blink code.

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.

This uses template and macro magic to reflect the fields of a class.
Dawn:
* Reflect the fields of the types that are used by Dawn's stream::Stream<T> specializations, and use tint::ForeachField() to call StreamIn().
Fuzzers:
* Replace tint::fuzzers::DataBuilder::BuildImpl<T> specializations with the new reflection system.
* static_assert that the type is either POD or reflected. Add a specialization for std::optional which was missing.
Move tint::transform::BindingPoints into MultiplanarExternalTexture, as this is only used by MultiplanarExternalTexture.
All this reduces fragility of the struct declarations slipping out of sync with the uses.
