Added function in node_id_map to check a given id is valid and fresh.
Currently, the structure of FindMutators declares node_id_map as const, which causes issues when we want to call `GetFreshId` from the argument that is passed by reference. A simple work around is to pass a non-const node_id_map as argument directly. That way `GetFreshId` function in node_id_map can continue to be non-const and conveniently update next fresh id whenever a fresh id has been taken.

Fix the infinite loop caused by 6e459fecb7.
That commit changed the behaviour of a sem::Statement::Block method for
sem::BlockStatement instances. Now, the method returns the block itself
instead of the outer block which causes an infinite loop when iterating

This reverts commit 5a53634764.
Reason for revert: This is making the Dawn -> Chromium roller fail.
https://github.com/KhronosGroup/SPIRV-Tools/pull/4407 introduces a new mandatory parameter to the spvtools::fuzz::Fuzzer constructor, which does not exist in Chromium's version of SPIRV-Tools (d9f89257855a2784323512cd9568b6610bcae581).
The roll of SPIRV-Tools into Chromium is currently blocked by another issue, and is a couple of weeks behind ToT. See https://autoroll.skia.org/r/vulkan-deps-chromium-autoroll.
Note, that https://github.com/KhronosGroup/SPIRV-Tools/pull/4407 is going to block the eventual roll of SPIRV-Tools in Chromium, as there's no way this code can compile for both pre and post roll.
I'll try and fix this after unblocking this roll

The SPIR-V Tools fuzzer asserts that the binaries it receives have sizes
that are multiples of 4 bytes, as it should only ever run on valid
binaries. This is failing in ClusterFuzz, likely due to the fuzzer being
misconfigured, so for now these assertions have been replaced with early
exits. They should be reinstated once the fuzzer is correctly
configured.

Adds assertions to check that the SPIR-V Tools fuzzer is not
inadvertently applied to SPIR-V binaries of an invalid size, which
guards against the fuzzer being run in a misconfigured fashion.
The CL also moves a memcpy that populates a SPIR-V binary buffer so
that the memcpy only happens when the input really is SPIR-V. This
avoids frequent redundant memory copies when fuzzing WGSL.

There's a lot of missing doxygen in the cli.h file. Add a TODO and disable it for now.

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.
