Changes various fuzz 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 a
ClusterFuzz bug reproducer does not use the required back-end command
line argument.

Fuzzers that exercise the SPIR-V reader are being moved to OSS-Fuzz.
This change removes them from the Chromium build so that they cease to
be run by ClusterFuzz. The change also applies a small refactoring to
the fuzzer build rules, so that the tint_ast_clone fuzzer is specified
together with other fuzzers that require the WGSL reader and writer.

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.

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.

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.

Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.
The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
var x : [[access(x)]] alias_to_struct;
Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.
Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.

Transforms are meant to be reusable. Those that hold state cannot be used concurrently.
State leakage between runs is dangerous.
To fix this:
* Add transform::Data - A new base class for extra information emitted by transforms.
* Add transform::DataMap - A container of Data, keyed by type.
* Add a transform::DataMap field to Transform::Output.
* Have FirstIndexOffset emit a FirstIndexOffset::Data.
* Deprecate the getters on the transform.
Mutability of the transform config is also dangerous as setters can be called while a transform is actively running on another thread.
To fix:
* Expose a VertexPulling::Config structure and add a constructor that accepts this.
* Deprecate the setters on VertexPulling.
Also deprecate Transform::Output::diagnostics.
Put all the transform diagnostics into the returned Program. Reduces error handling of the client.

Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.
As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.
As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.

Despite `tint::ast::type::Type` being in the AST namespace, these classes are clearly not AST nodes:
* They don't derive from ast::Node
* They're deduplicated by the type manager
* None of the types have an Source - they have no lexical declaration point
* The fact we have `ast::Struct` and `ast::type::Struct` clearly demonstrates what is an AST node, and what is a type.
* We have code scattered in the codebase (TypeDeterminer, writers, etc) that create new types after parsing - so clearly not part of the original syntax tree.
Types in tint are closer to being semantic info, but due to the parse-time generation of types, and tight dependency of ast::Nodes to types, I'd be reluctant to class these as semantic info. Instead, put these into a separate root level `tint::type` namespace and `src/tint` directory.
The fact that types exist in the ast::Module has already caused bugs (https://dawn-review.googlesource.com/c/tint/+/37261). This is a first step in separating out types from the ast::Module.

A container and allocator of objects of (or deriving from) the template type `T`.
Objects are allocated by calling Create(), and are owned by the BlockAllocator.
When the BlockAllocator is destructed, all constructed objects are automatically destructed and freed.
Objects held by the BlockAllocator can be iterated over using a View or ConstView.
Use this to hold the ast::Nodes in the ast::Module
This is called BlockAllocator as it can be optimized to hold objects in contiguous memory blocks, which will improve cache coherencey. Currently BlockAllocator is a straight port of the vector-of-unique-ptr, taken from ast::Module.
