Remove support for building Alpha/PR (adhoc) builds.

We've haven't really been using these and they're proving to be quite a chore to keep running.
Also, we recently needed an external demo build and we chose to go with custom build on top of testflight instead.

As such it's been decided that we can go ahead and remove them.
