EmitVertexPointSizeTransform is a Transformer that adds a PointSize builtin global output variable to the module which is assigned 1.0 as the new first statement for all vertex stage entry points.
If the module does not contain a vertex pipeline stage entry point then then this transformer is a no-op.

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.

They already exist in a `ast::type` namespace, so `ast::type::BlahType` is just stuttering.
This is more important now that Is<> and As<> use the full type name.

aliased structs remains to allow for migration to the new system. The

This CL moves the StructType name into the constructor of the struct
type instead of receiving through an accessor. The |set_name| accessor
is removed as it should not be needed anymore. All call sites have been
updated.
The vertex pulling transform was fixed to correctly register an alias
for the structure being created so it will be emitted.
