Remove ageing transform dialect extensions (#909)

Our own transforms are now being used as passes and the transform ops
are unmaintained for a while and not helpful any more. We plan to
restart working on transforms later on, but we'll certainly approach it
form an upstream-first mindset, so likely not to use the custom ops we
created.

However, they have served their purpose. They allowed us to experiment
with IR at a time when we didn't have such a mature dialect / pass
environment.

For those wanting to get these back, they can just revert this commit on
a branch and work with the code locally, but I strongly suggest to only
use these as a baseline, not as forward looking code.
