Alastair Donaldson 08146e2300 Fixes for 32-bit build of fuzzers
This change resolves some type-related issues that were leading to
loss-of-precision warnings when compiling for i386 in OSS-Fuzz.

Ryan Harrison 71763c84c2 Update remaining fuzzers to use TransforBuilder
Missed some fuzzers in my last fix, because I was trying to git grep
between repos...

This should fix any outstanding issues with
NULL being passed into SetTransformManager in TintCommonFuzzer.

Alastair Donaldson 8b2181c98f Change injected failure from assert to abort
An assertion failure had been injected to check that black box fuzzing
is working, but as ClusterFuzz runs a release mode build this was not
triggering. This change turns the assertion failure into an abort. Once
it has been established that the abort is triggered by the black box
fuzzers, it should be removed.

This commit introduces a `State` object to this transform, which is

Alastair Donaldson 4d18c6b7c5 spirv-tools fuzzers: Avoid passing target backend
Changes the spirv-tools fuzzer targets so that the target back-end
language (HLSL, MSL, SPIR-V or WGSL) is no longer passed as a command
line argument, but instead baked into the fuzzer's binary. This avoids
a problem whereby an OSS-Fuzz bug reproducer does not use the required
back-end command line argument.

Alastair Donaldson 871570bc7b Tolerate some errors while building SPIR-V corpus
When preparing a corpus of SPIR-V shaders for fuzzing, spirv-as is
invoked repeatedly. It could be that a bug in spirv-as leads to
conversion failing for some of the shaders. This should not prevent the
overall corpus from being generated, as long as the number of overall
failures is reasonably small. This change adds some tolerance for such
failures.

James Price acaecab29d msl: Handle workgroup matrix allocations
Use a threadgroup memory argument for any workgroup variable that
contains a matrix.

The generator now provides a list of threadgroup memory arguments for
each entry point, so that the runtime knows how many bytes to allocate
for each argument.

James Price c306cda4db inspector: reflect num_workgroups builtin usage
Dawn needs to know if a given entry point uses this builtin, so that
it can pass this information via a root constant for HLSL.

James Price 922fce7295 Implement and test num_workgroups for all backends
For HLSL, use the new NumWorkgroupsFromUniform transform, and expose
the binding point to use for the generated uniform as a backend
option.

The MSL mapping is trivial, and it was already implemented for WGSL
and SPIR-V.

James Price 77a25c060f transform: Add NumWorkgroupsFromUniform transform
This transform scans entry points for struct parameters that contain
the num_workgroups builtin, and replace accesses to these members with
a value loaded from a uniform buffer.

This will be used by the HLSL backend to implement the num_workgroups
builtin.
