Revert RIT changes from release branch

[rileykarson]

The GA API seems to have gone away- revert the whole feature (including beta)

git revert a97d0c89ed1842c9d21717c9387ba3595adf9742
git revert d9a84b596755d154872ec5c3a357e3459c001545

Note that d9a84b5 was an unclean revert due to #14128

Release plan:

• Merge these changes
• Run TestAccCompute against the release branch (~2h)
• If successful, release tomorrow
