7eb37948ab tint/reader/wgsl: Have expect_identifier return an ast::Identifier
Instead of a std::string. This avoids unnecessary string allocations, and follows the pattern of all other AST nodes.

79781f26d1 tint: Unkeyword 'var' template args
Change the address space and access mode in ast::Var from enums
to Expressions. Have the resolver resolve these, like we do for
other template arguments.

As the AST nodes now have identifier expressions, the tint-internal
'in' and 'out' address spaces have been prefixed with underscores to
prevent input code from using this.

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.

d9f659670d tint: Handle @diagnostic on block statements
Use expect_compound_statement() in all the places that use
compound_statement in the WGSL grammar.

Handle attributes on statements inside Resolver::StatementScope, so
that the logic can be reused for the various places where block
statements are used. This will also make it easier to reuse this logic
when we allow these attributes on other types of statement in the
future.

Add an `EmitBlockHeader()` helper to the WGSL writer to reuse the
logic for emitting attributes on block statements for all the places
that use them.

a838e34954 Handle peeking past placeholder elements.
Currently when peeking, if there is placeholder then anything after
the `peek(0)` will be off by 1 position as the placeholder will
end up included in the index count.

This CL updates the peek routine to correctly skip over any
placeholder element between the current index and the requested
peek token.

158c85dab4 Add new relational rules to WGSL grammar.
This CL adds the `relational_expression.post.unary_expression` grammar
rule into the WGSL parser. A `shift_expression` helper and a
`relational_expression` helper are also added.

Note, the two helpers have `maybe_` as name prefixes. This will be
dropped when the old parser path is removed which current uses the
other versions of those names.
