Transforms are meant to be reusable. Those that hold state cannot be used concurrently.
State leakage between runs is dangerous.
To fix this:
* Add transform::Data - A new base class for extra information emitted by transforms.
* Add transform::DataMap - A container of Data, keyed by type.
* Add a transform::DataMap field to Transform::Output.
* Have FirstIndexOffset emit a FirstIndexOffset::Data.
* Deprecate the getters on the transform.
Mutability of the transform config is also dangerous as setters can be called while a transform is actively running on another thread.
To fix:
* Expose a VertexPulling::Config structure and add a constructor that accepts this.
* Deprecate the setters on VertexPulling.
Also deprecate Transform::Output::diagnostics.
Put all the transform diagnostics into the returned Program. Reduces error handling of the client.

Have the TD resolve swizzles down to indices, erroring out if they're not valid.
Resolving these at TD time removes swizzle parsing in the HLSL writer, and is generally useful information.
If we don't sanitize in the TD, we can end up trying to construct a resulting vector of an invalid size (> 4) triggering an assert in the type::Vector constructor.

This fixes issues where the reording might generate an invalid WGSL

This also unifies the implementation of Generate() and

Make private all TypeDeterminer::DetermineXXX() methods, forcing all tests to use the root-level TypeDeterminer::Determine() method.
Remove TypeDeterminer::RegisterVariableForTesting().
The main use for calling the TypeDeterminer::DetermineXXX() methods was to perform type determination on a partial AST.
This was messy and often resulting in multiple calls into TypeDeterminer. Most tests already perform a full TypeDeterminer::Determine() call when the program is built, so many of these were redundant.
The exposure of these internal methods for testing also makes refactoring the TypeDeterminer extremely difficult.
Add a number of ProgramBuilder helper methods for attaching the partial AST in these tests to the root of the AST, greatly simplifying the use of the TypeDeterminer:
* ProgramBuilder::Global() and ProgramBuilder::GlobalConst() are helpers that register the variable returned by ProgramBuilder::Var() and ProgramBuilder::Const(), respectively.
* ProgramBuilder::WrapInFunction() is a variadic function that accepts variables, expressions and statements, attaching these to the root of the AST via a dummy function.
Most test classes now no longer use their own TypeDeterminer, and instead properly depend on the automatic type determination performed at Program build time.

Program is now immutable*, and remains part of the public Tint
interface.
ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.
Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().
Mutable ProgramBuilders can be moved into immutable Programs.
* - mostly immutable. It still has a move constructor and move
assignment operator - required for practical usage - and the
semantic information on AST nodes is still mutable.

Use the new type::Manager::Wrap() function to build a new temporary type manager that wraps the program's type manager.
This allows the writer to construct temporary new types (if they weren't already in the program) without actually mutating the program.

Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.
As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.
As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.

For now, have Program be a simple wrapper around ast::Module so we can migrate Dawn's use of the public tint API.
Add new Program variants of public APIs for places that returned or took a Module.
Remove Reset() methods from Generators, they aren't used, and make the migration harder.

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.
