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.
