The error type will help distinguish between validation errors, context losts and others which should be handled differently. Take advantage of advantage of this to change DAWN_RETURN_ERROR to "return DAWN_FOO_ERROR" to have the return be more explicit. Also removes usage of DAWN_TRY_ASSERT for more explicit checks.
