This CL updates the if and switch nodes to store the condition value in
a register. The EmitExpression is updated to return a Register and the
builder updated to emit the expressions for the if, break-if, while,
and switch expressions.

This patch updates the validations about CreateBuffer() with dawn_wire
to match the latest WebGPU SPEC.
According to the SPEC, the validations in CreateBuffer() should be
executed in the below order:
1. If mappedAtCreation == true, return nullptr and a RangeError will be
generated in Chromium.
2. Validate BufferDescriptor and check if there is OOM at device timeline
3. Check if there is OOM at content timeline

Pads serialized wire command buffers to 8 bytes so that we don't have
misaligned write/reads which can cause SIGILL depending on platform and
compilation mode, i.e. -c dbg in google3 builds.
- Adds helpers for aligning sizeof calls.
- Adds constant for wire padding (8u).
- Modifies BufferConsumer to allocate according to padding. This
guarantees that when we [de]serialize stuff, the padding should be
equal on both sides.
- Modifies extra byte serialization code (adding CommandExtension
struct). This makes it clearer that each extension needs to be
padded independently. Otherwise, before in wire/client/Buffer.cpp,
since the read/write handle sizes were being passed as a sum, but
read out separately from the BufferConsumer, we corrupt our pointers.
- Adds some simple unit tests.

Sync up with current WebGPU spec to allow FS input being a
subset of VS output instead of requiring a strict match.
This patch involves changing the validation and adding tests,
together with using the TruncateInterstageVariables for hlsl
generator to workaround the extra limit for D3D12 backend.

Add a transform to truncate unused user interstage variables by
adding a new truncated shader io struct wrapper of the original
one, with a truncate function to do the assignments called
at the return statement.
This transform is meant to be run after CanonicalizeEntryPointIO,
and will only be run under hlsl/generator_impl.cc to workaround
the extra register limitation for interstage variables on D3D FXC.

This CL renames the `Build` method in the test helper to be
`CreateBuilder` to maek the intention clearer. A second,
`CreateEmptyBuilder` is provided to allow for easier testing of
expressions.
The `current_flow_block` and `builder` are moved to public so they can
be used/updated during testing.

Update CreateASTTypeFor() to handle a potential edge-case described in tint:1764.
We haven't seen this issue happen in production, nor can I find a way to trigger this with the tint executable, but try to handle this before we encounter a nasty bug.

There's a reason the overload of `ctx.Replace()` that takes a pointer to the replacement is deprecated - it doesn't play well when used as part of another replacement.
Switch to using the callback overload of Replace() to fix bad transform output.

The SingleEntryPoint transform currently does not strip away any
unused type declarations, which was leading to broken code when an
alias referenced an override that was removed. We can detect this
scenario and remove such aliases, until we have a better mechanism for
detecting all unused aliases.
