chore(tvix): Use StatusOr API available in Abseil's version r/1888

The Abseil version of `StatusOr` does not come with the status macros
or the `Consume*` family of functions.

This change modifies the existing code to use the common denominator
of the API that is available between Abseil's own implementation of
`StatusOr` and the one from Tensorflow that we are currently using.
