This change implements a new fuzzer. It mutates a WGSL shader by traversing
the AST of a program and applying various transformations that might or might not
be semantics preserving.

This change adds a new tint fuzzer that uses SPIRV-Tools to fuzz SPIR-V binaries.
The fuzzer works on a corpus of SPIR-V shaders. For each shader from the corpus it uses
one of `spirv-fuzz`, `spirv-reduce` or `spirv-opt` to mutate and then runs the shader through
the Tint compiler in two steps:
- Converts the mutated shader to WGSL.
- Converts WGSL to some target language specified in the CLI arguments.
The list of all supported CLI arguments and their description is in the cli.h file.

* Disable "undefined-var-template" in code, rather than in build files
* Add back some missing headers required when building in this context
* Make sure gtest/gmock do not override the default runtime library

This CL moves spirv-tools so that it will only build what is requested.
This means that the tool binaries will not be built as part of tint as
they aren't needed.

- Add googletest and spirv-tools local builds only if their CMake targets
are not already configured.
- Add local spirv-headers as an include directory only if the associated
CMake directory does not already point to a directory.
