This CL removes the override emission from the GLSL backend. The
override should be removed by the substitute_override transform
before making it to the backend.

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.

This CL updates the internal storage for a `@location` attribute
to store the `Expression` instead of a raw `uint32_t`. The current
parser is updated to generate an `IntLiteralExpression` so we still
parse as a `uint32_t` at the moment.

Remove the old backend specific implementation for
overrides. Use tint SubstituteOverride transform to replace
overrides with const expressions and use the updated program
at pipeline creation time.
This CL also adds support for overrides used as workgroup size
and related tests. Workgroup size validation now happens
in backend code and at compute pipeline creation time.

During some transforms we may move an entry point parameter to
a global variable. This means the global may now have a Location
attached where it isn't permitted by the WGSL spec.
This CL adds a `location` to the GlobalVariable sem value and
populates it in the resolver.

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.

These can be used in all sorts of places which are not tracked by sem::Function::TransitivelyReferencedGlobals().
As they're not emitted as variables by any backend, just preserve them.

This CL adds the `@location` of a Struct Member into the
`StructMember` sem object as a `std::optional<uint32_t>`. The
resolver then populates the location value if an attribute is
found during resolution.
This will provide a place to store the evaluated expression value
for a location in the future.

Modify the AddSpirvBlockAttribute transform to fix top-level structure
access of uniform, storage and push-constant buffers for use in the
GLSL backend. The small change to the transform makes the transform
wrap host-sharable buffers, if they're also used as a
non-host-sharable structure. Also rename the transform to
AddBlockAttrbibute in order to reflect its wider applicability.

If the let initializer was an abstract numeric that was implicitly materialized to a concrete type, then we could inlining the initializer into the use without the implicit materialization cast.
This could lead to validation errors, and subtly different results in the program.
In this situation, add an explicit cast to keep the types the same before and after inlining.

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.
