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.

The single DAWN_ENABLE_OPENGL flag in the root CMakeLists.txt did not define
DAWN_ENABLE_BACKEND_DESKTOP_GL or DAWN_ENABLE_BACKEND_OPENGLES, so examples
with `-b opengl` reported `Backend isn't present` and failed to start.
ENABLE_OPENGL flag in root CMakeLists.txt was replaced by ENABLE_DESKTOP_GL
and ENABLE_OPENGLES flags, repeating the logic of similar flags
in GN buildsystem as done in src/common/BUILD.gn
and scripts/dawn_features.gni.

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.

Deep-clones all `Node`s and `Type`s into a new module.
Instead of writing a million standalone tests that'll only ever test the
existing fields of each type, I've opted to write the tests using
wgsl<->ast<->wgsl conversion. This means the tests require the enabling
of TINT_BUILD_WGSL_READER and TINT_BUILD_WGSL_WRITER, but I believe this
is much easier to maintain.
I'm aware there are probably gaps in the tests, and that even full
coverage is likely to rapidly rot, so I've also added
fuzzers/tint_ast_clone_fuzzer.cc - a fuzzer based test that ensures that
all AST modules can be cloned with identical reproduction.
I've run this across 100 cores of a 3990x for 4 hours, fixing the
single issue it detected.
Note: Expressions do not currently clone their `TypeManager` determined
types. This is for two reasons:
(a) This initial CL is mahoosive enough.
(b) I'm uncertain whether we actually want to clone this info, or to
re-run the `TypeDeterminer` after each AST transform. Maybe it should
be optional. Time will tell.

the implementation of the wire, renames dawn::wire to dawn_wire, moves
src/wire to src/dawn_wire and puts the interface of dawn_wire in
src/include/dawn_wire.
libdawn will be one of the libraries produced but other libraries like
libdawn_native don't need to link against it. However they do need the
Dawn headers so we generate them separately.

The defaults were setting local variables, while the "option" command
uses the values from the CMake cache. This made the CI not build the

This helps Visual Studio users have less clutter in their solution

This macro has some advantages over the standard library one:
- It prints the place where the macro was triggered
- It "references" the condition even in Release to avoid warnings
- In release, if possible, it gives compiler hints

This directory used to contain both the state tracking code for the

- src/common is utility code for the whole repo
- src/backend contains libNXT's code
