This CL adds support for the decorated texture storage tokens. The old
_ro_ and _wo_ tokens still exist until downstream users are updated.

This moves the usage of Tint in the fuzzers into a single class. This
will be expanded in the future to support emitting shaders, so fuzzing
tests, just need to indicate which reader & writer they want to use,
instead of having each test implement all of the API usage logic
directly.

Demangle the printed AST before comparing.
Many to_str() methods on AST nodes will print the symbol numerical identifiers, which is not guaranteed to be stable between clones.
By comparing the demangled AST, these should be stable.

This CL removes all internal usage of the Context object. It is still
accepted as a parameter until we update Dawn, but all usage is removed.
The namer has been removed from the SPIR-V backend with this change and
the emitted names reverted to their non-modified version.

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.

Without this the fuzzing is unguided and takes exponentially more time to find interesting corpus cases.

This is the first step in improving the error messages produced while parsing.
The `line` and `column` information of `Source` has been moved to `Source::Location`.
`Source::Range` has been added that contains a `Location` interval - allowing error messages to highlight the full region of the error.
The `File` information provides an optional file path, and pre-splits the content into lines. These lines can be used to print the full line containing an error.
This CL contains a few temporary changes that help split up this work, and to ease integration with Tint.
