The runtime toggle is off by default. When turned on,
the deprecation warning will be turned into validation error.
Replace device->EmitDeprecationWarning with
DAWN_MAKE_DEPRECATION_ERROR macro which make an internal
validation error or make a MaybeError{} based on the toggle.
The callsite can wrap it with a DAWN_TRY.
