This is a public API breaking change, so I've added the `DAWN_USE_NEW_TINT_TRANSFORM_API` define which is used by Dawn to know which API to use.
As we're going to have to go through the effort of an API breaking change, use this as an opportunity to rename Transformer to Transform, and remove 'Transform' from each of the transforms themselves (they're already in the transform namespace).

ReplaceAll() registers `replacer` to be called whenever the Clone() method is called with a type that matches (or derives from) the type of the first parameter of `replacer`.
`replacer` must be function-like with the signature: `T* (T*)`, where `T` is a type deriving from CastableBase.
If `replacer` returns a nullptr then Clone() will attempt the next registered replacer function that matches the object type. If no replacers match the object type, or all returned nullptr then Clone() will call `T::Clone()` to clone the object.
Example:
```
// Replace all ast::UintLiterals with the number 42
CloneCtx ctx(mod);
ctx.ReplaceAll([&] (ast::UintLiteral* in) {
return ctx.mod->create<ast::UintLiteral>(ctx.Clone(in->type()), 42);
});
auto* out = ctx.Clone(tree);
```
This is to be used by Transforms that want to replace parts of the AST on clone.

We're seeing some chrome bots fail unittests in ways that suspiciously
look like dynamic casts are doing Wrong Things.
The ClassID::Of() logic depends on the linker folding away duplicate
compilation unit definitions based on ODR rules. If we were to somehow
end up with different definitions, then we'd have two or more different
ClassIDs for the same T type - leading to issues similar to what we're
seeing.
I'm not entirely sure why/how this could happen - and we've so far been
entirely unable to locally reproduce - but it _might_ have something to
do with the goma cache.
In an attempt to work around this, move the static symbol definition out
of a header-local-static and into the .cc file for each of the types.

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.

Implements `As<Blah>()` and `Is<Blah>()` automatically.
There are several benefits to using this over the pattern of hand-rolled `IsBlah()`, `AsBlah()` methods:
(1) We don't have to maintain a whole lot of hand written code.
(2) These allow us to cast from the base type to _any_ derived type in a single cast. The existing hand-rolled methods usually require a couple of intermediary casts to go from the base type to the leaf type.
(3) The use of a template parameter means these casts can be called from other template logic.
Note: Unlike the hand-rolled `AsBlah()` methods, it is safe to call `As<T>()` even if the type does not derive from `T`. If the object does not derive from `T` then `As` will simply return `nullptr`. This allows the calling logic to replace the common pattern of:
```
if (obj.IsBlah()) {
auto* b = obj.AsBlah();
...
}
```
with:
```
if (auto* b = obj.As<Blah>()) {
...
}
```
This halves the number of virtual method calls, and is one line shorter.

Add `tint::writer::FloatToString()`:
Converts the float `f` to a string using fixed-point notation (not scientific).
The float will be printed with the full precision required to describe the float.
All trailing `0`s will be omitted after the last non-zero fractional number,
unless the fractional is zero, in which case the number will end with `.0`.
Use this for the wgsl, msl and hlsl backends.

This CL updates the binary operator emission to use the `mul()` method
in the following cases:

This is because the `*` operator works per-component in HLSL which does

The reason being that some tests called parse() twice, which will silently destruct the first parser.
Once the `Module` owns the AST nodes, the second call will end up deleting all the AST nodes. Tests would then perform use-after-free for the AST nodes belonging to the first parser / module.
There's no reason why the unique_ptr can't be returned, which is cleaner overall.

Add C++ aliases for the wgsl types `i32`, `u32` and `f32`.
Separate types out from the builder and into a `Builder::Types` class. An instance of this is now held by the `Builder::ty` field. Makes it clear when you are referencing a `ast::type` instead of a constructor method.
Rework a number of builder methods so they take the type as a template argument instead of a parameter. This more closely resembles wgsl (example: `vec2<i32>(1,2)`)
Use PascalCase for the constructor methods, but keep the wgsl-like constructors lowercase to imitate the language style.
Add `BuilderWithContext` so that `Builder` can be truely immutable, and so we can remove `set_context()`.

Remove all redundant std::move()s. I've also removed calls to
std::move() in tests, even if they act as an optimization. This is for
two reasons:
(a) Performance is not important for testing, and this helps with
readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
they can be repopulated and used again. This is undefined behavior:
> Objects of types defined in the C++ standard library may be moved from
> (12.8). Move operations may be explicitly specified or implicitly
> generated. Unless otherwise specified, such moved-from objects shall
> be placed in a valid but unspecified state.
All of these UB cases have been fixed.

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.

Produce less noise in ASTs for a common case.
Also test that an empty continuing construct doesn't show up in the
AST. That's currently handled by the AST code. We want to keep this
behaviour even if the AST implementation changes. Right now
code change is needed when emitting the start of a continuing
