This implements the uniformity analysis as currently described in the
WGSL specification. Uniformity issues are presented as warnings, and
will be switched to errors in a future release.
A follow-up patch will improve the error messages, which currently
just show the point at which a uniformity was detected.
In a future release, once we have obtained initial feedback from
users, uniformity issues will become errors.

There is currently a race condition in the metal backend with the
updating of `mCompletedSerial`. It is currently possible for the
`addCompletedHandler` to set to one value and then have the
`CheckAndUpdateCompletedSerial` call immediately set it back to
a lower value. This can then cause hangs as the serial never
correctly updates again.
This was happening on `dawn.node` when running a large number of
CTS test cases all at the same time.

This is done via a new extension, which in the future could also be
used by shader authors as an escape hatch while we are still refining
the analysis.
The transform is run by the sanitizers for all of the non-WGSL

Generate different tokens for:

• unsuffixed integer literals
'f' and unsuffixed are currently both treated as f32 by the resolver,
but this is the first step to supporting abstract floats.

Tint has already implemented the enable directive for using WGSL
extension in the future, and using a WGSL extension that is not allowed
for the device should result in a shader creation error.
In this patch a WGSL extension allow list is added in DeviceBase, and
a validation is added in shader module base initialization to make sure
all extensions used in the WGSL program are in the allow list. This
patch also rename the `ValidateShaderModuleDescriptor` to
`ValidateAndParseShaderModule`, which is more descriptive for what it
actually does.

This change ensures that when errors are raised from WebGPU, including
lost context errors, they can include any associated Vulkan validation
layer messages in the message text if backend validation is enabled.
This will allow these messages to be surfaced in places like when
running CTS tests on browser build infrastructure.
Because of how Vulkan messages are raised at the instance level, some
routing of the messages to the appropriate device needed to be added.
This is based on appending message IDs to object labels and then parsing
them out of the message when it comes in.
This change also makes Vulkan validation messages cause a device loss,
which is inline with the behavior of the D3D12 backend.

Merge SintLiteralExpression and UintLiteralExpression with
IntLiteralExpression. IntLiteralExpression has a new Suffix field which
indicates whether the literal is either a:
• 'i' suffixed integer literal
• 'u' suffixed integer literal
• no-suffix integer literal
Have the SPIR-V reader produce no-suffixed literals for i32 types, to
keep this change small. In future changes the SPIR-V reader will
produce 'i' suffixed types for these.
Have all consumers of IntLiteralExpression treat unsuffixed integers the
same as 'i'-suffixed literals. Unsuffixed will be treated as abstract in
future changes.
Removed SemHelper::TypeOf(const ast::LiteralExpression* lit).
