The shader source can be very large and this is causing excessively
large error messages that get truncated in some applications that use
Dawn native. We don't need to see the whole shader in the error
message.

This patch:
1. Add the `f16` WGSL extension.
2. Add `f16` as keyword, and remove it from reserved word list.
3. Add ast::f16 and sem::f16, and implement validation that using `f16`
type must be with `f16` extension enabled.
4. Add `Number<NumberKindF16>` for f16 literal and constant, and add
`ast::FloatLiteralExpression::Suffix::kH`.
5. Add placeholder in all writer which report error when try to emit f16
type.

The WebGPU spec says that a validation error is produced if there is a
color target in the pipeline descriptor that has writeMask!=0 while
there are no shader outputs for this target. In Dawn format==undefined
is used as a tag that the color target is not present, so writeMask is
allowed to be 0 if format==undefined. (the validation in the case where
format!=undefined was already present).

If the function has no return statements, we need to do this to
capture the potential non-uniformity coming from nested function
calls.
This also removes the need to add explicit edges for discard
statements, so remove them.

Chromium tracks the devices which live on the wire so it can
automatically call tick on devices that have pending work. This used
to be done by querying an (id, generation) pair and checking if it
resolves to a non-null device.
This CL adds a new way to query directly using the device, since a
refactor in Chrome will change creation such that the id and generation
is not known when a new device is requested.
Also fixes a bug for device callbacks where the required callback
userdata wasn't fully populated for devices created with
requestAdapter. Update a test to check for this as well.

When producing an error from the uniformity analysis, add notes to
show the underlying reason for the uniformity requirement.
For function calls that are required-to-be-uniform, show the innermost
builtin call that has the requirement.
For function parameters that are required-to-be-uniform, recurse into
that function to show where its requirement comes from.
Add some new tests to specifically test the error messages.

Move the control flow graphs to `FunctionInfo` so that they are not
destroyed when we finish processing the function.
This will make it easier to produce more detailed diagnostics for
uniformity issues, which will be coming in subsequent CLs.
There is no functional change in this CL.

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.

• unsuffixed integer literals
'f' and unsuffixed are currently both treated as f32 by the resolver,
