James Price 7d2e204911 [tint] Move AST transforms to a subdirectory
This prepares for the addition of IR transforms. Subsequent patches
will introduce an ast::transform namespace and refactor the Transform
class into a common base class for the two types of transform.

This CL consolidates the unicode code into utils. These are utility
libraries, so the extra namespace doesn't add much.

dan sinclair 39d4065653 Move BindingRemapper and MultiplanarExternalTexture to a backend transform.
In most backends, MultiplanarExternalTexture must run before the
BindingRemapper. The exception is the Vulkan SPIR-V backend where
it has to run before Multiplanar. This CL moves both of the transforms
to backend transforms and sets up the ordering as needed in the
generators.

builtin uniforms, structs, some builtin functions, zero initialization

unimplemented. All the unit tests "pass", but the output is not correct
in many cases.

triangle.wgsl outputs correct vertex and fragment shaders that pass
GLSL validation via glslang. compute_boids.wgsl outputs a valid but not
correct compute shader.

James Price dc8f08a782 [msl-writer] Use entry point interface canonicalization transform
This replaces the entry point IO component of the MSL sanitizing
transform, and completes support for the new entry point IO syntax.

Struct emission in the MSL writer is updated to use the correct
attributes depending on the pipeline stage usage.

Ben Clayton 207b5e2de1 Move tint::ast::type to tint::type
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.

Ben Clayton 00b77a80ab Rework all transforms to transform-on-copy
instead of transform-in-place.

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).

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.
