971318f7a2 tint: Replace all remaining AST types with ast::Type
This CL removes the following AST nodes:
* ast::Array
* ast::Atomic
* ast::Matrix
* ast::MultisampledTexture
* ast::Pointer
* ast::SampledTexture
* ast::Texture
* ast::TypeName
* ast::Vector

ast::Type, which used to be the base class for all AST types, is now a
thin wrapper around ast::IdentifierExpression. All types are now
referred to using their type name.

The resolver now handles type resolution and validation of the types
listed above based on the TemplateIdentifier arguments.

Other changes:
* ProgramBuilder has undergone substantial refactoring.
* ProgramBuilder helpers for type inferencing is now more explicit.
  Instead of passing 'nullptr', a new 'Infer' template argument is
  passed.
* ast::CheckIdentifier() is used for more tests that check identifiers,
  including types.

ce31d187ef tint/ast: Change Function::symbol to Function::name
Function::name is an ast::Identifier.

The goal here is to have all AST nodes use an identifier instead of
symbols directly. This will greatly simplify the renamer transform,
and gives the symbol a Source location, which is helpful for
diagnostics and tooling.

1906857a50 tint: Remove ast::Void
WGSL does not have a void type. Functions that do not return a value
simply omit the return type from the function signature.

4a92a3c904 tint: Optimize sem node lookup
Add a 'NodeID' to each ast::Node which is the sequentially allocated
index of the node. Use this in sem::Info to map the AST node to the
semantic node, instead of using a std::unordered_map.

Optimised very hot code by entirely eliminating map lookups, and
dramatically reducing cache misses (lookups are usually sequentually
ordered).

Timings running
'webgpu:shader,execution,expression,call,builtin,atan2:f32:inputSource="const";vectorize="_undef_"'
with dawn/node, using SwiftShader:

dcdf66ed5b tint/ast: Derive off ast::Variable
Add the new classes:
* `ast::Let`
* `ast::Override`
* `ast::Parameter`
* `ast::Var`

Limit the fields to those that are only applicable for their type.

Note: The resolver and validator is a tangled mess for each of the
variable types. This CL tries to keep the functionality exactly the
same. I'll clean this up in another change.

ast::Variable up, this will become a different vector type.

41e4d9a34c Consistent formatting for Dawn/Tint.
This CL updates the clang format files to have a single shared format
between Dawn and Tint. The major changes are tabs are 4 spaces, lines
are 100 columns and namespaces are not indented.
