With the change to remove support for `Override` in the various
backends, it is now possible for the fuzzers to send invalid programs
through to the generators by creating overrides.
This CL adds the `SubstituteOverride` transform into the fuzzers and
defaults any non-initialized override to 0. The transform is run
separate from the other transforms used by the fuzzers as the fuzzers
don't have to add transforms, this makes sure the substitution always
happens, regardless of other transform configuration.

Fixes the regex fuzzer so that when searching for an operator to
replace, it takes account of the fact that the string being searched may
be very small, avoiding an issue where unsigned integer underflow would
occur.

• Add `cts validate` command used to check for expectation collisions.
Can be used as a presubmit check.
This is more tightly checked than the previous logic, as this works on just
the expectations, instead of results.
• Fix an issue where the test result reduction could introduce collisions with
'Skip' expectations.
To fix this, the update process first adds 'consumed' results for the skipped
tests, preventing test tree reduction for that part of the tree.
• Fix a bug in the generation of 'New failures' and 'New flakes' which produced
more expectations than was necessary.
The issue here was that the tree roots could contain overlaps, and roots could
be processed before sub-trees, resulting in inefficient expectations.
• Fix collisions in the expectations file, and update with results from
the most recent roll.

Shuffle the transform orders to ensure that these are embedded in a structure before running the Std140 transform.
Add more end-to-end tests for these.
As pointed out in tint:1673, arrays of matrices are not correctly decomposed by the Std140 transform.
This will be addressed by a later change.

We already compute the "first" and "last" basic block that
uses a value, so we could know when to hoist a value into
a var declaration. You have to do this sometimes to make
sure all uses are in scope of the declaration.
Until now we tracked Phis with an entirely different mechanism.
But there are cases which broke down. That's what happens
in crbug.com/tint/1649.
Additionally, GraphicsFuzz cases generarte similar weirdness.
Also, be more careful about ensuring that the assignments
generated to feed phis behave as if they occur in parallel.
Within a single batch of such assignments, generate and
use intermediate let-declarations for phis that that batch
will overwrite.
Also, unwrap-references when rectifying the signedness of
binary operators.

Metal configures the query set and query index for the beginning and end
of passes in pass descriptor when beginning a pass encoder, so we need
to record all timestamp writes information in BeginXxxPassCmd. For the
platfroms that support timestamp query, it must support timestamp write
at command boundary or stage boundary, if the stage boundary is
supported, use sampleBufferAttachments API for Metal implementation,
otherwise simulate timestamp write using sampleCountersInBuffer API
after begining a pass and before ending a pass.

This removes a serialization optimization where structs could be
memcpy'ed. memcpy is still used for deserialization of structs.
Structs may contain padding bytes which when copied can leak
uninitialized data across a trusted boundary. In Chrome, this
means previously-written or uninitialized bytes in the GPU process
could leak into the Renderer process.
In the future, we may be able to bring this back by introducing
a concept of safe-to-memcpy structs, or by forking the code so
that Renderer->GPU process uses the unsafe memcpy, and
GPU->Renderer uses to the safe member-by-member version.
An alternative might be to ensure that everything returned from
the WebGPU API has initialized padding, but this invariant is not
trivial to guarantee.

Also, set the VkShaderModule label before cache deduplication since to

may_exonerate indicates that a test failed for a known issue that
we could exonerate. Merging of test results now removes results
with may_exonerate unless all of them were tagged as such. So, if
for example, a test fails for a known timeout issue, but has a
subsequent pass, the timeout will be ignored.
This serves to reduce the impact of known, hard-to-fix issues and
allow the CTS roller to make progress with less noise.

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).
