test: Generate expected output for all tests The expected output is far from perfect, and the generated HLSL and MSL isn't even validated yet, so may be incorrect. However, by committing the generated output, we get clear examples of the currently generated output of each backend. As we land fixes and improvements to each backend, the presubmits will require us to update the expected test output, and so code reviews will include diffs of each backend's generated output.

ast: Support non-literal workgroup_size parameters 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.
