The effect to the user is the same, the Dawn device gets lost. However
we need to make the difference internally because when the backend
device is lost we can clean up immediately. On the contrary on internal
errors, the backend device is still alive and processing commands so we
need to gracefully shut it down.

The way in which the Result class is used in Dawn can be fragile
with respect to memory management because the caller of AcquireError
must know they need to delete the returned pointer or a memory leak
will occur. We've had a couple of instances where developers have
accidentally left out the delete call and managed to get past code
review.
This CL changes the Result class so that it assumes the error is
allocated on the heap and forces the caller to use unique_ptr when
calling AcquireError.

This same callback will be used for push/pop error scope.

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.
