Change the type of the values in an ast::WorkgroupDecoration to be
ast::Expression nodes, so that they can represent both
ast::ScalarExpression (literal) and ast::IdentifierExpression
(module-scope constant).
The Resolver processes these nodes to produce a uint32_t for the
default value on each dimension, and captures a reference to the
module-scope constant if it is overridable (which will soon be used by
the inspector and backends).
The WGSL parser now uses `primary_expression` to parse arguments to
workgroup_size.
Also added some WorkgroupSize() helpers to ProgramBuilder.

and ignored.
The parsers will be updated with future changes to stop creating these
semantic types.
Resolver creates semantic types from the AST types. Most downstream
logic continues to use the semantic types, however transforms will now
need to rebuild AST type information instead of reassigning semantic
information, as semantic nodes are fully rebuilt by the Resolver.
