Make Dawn error macro more explicit and have an "error type"

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.
