censor: implement censoring for revlogv2

It is a bit verbose and rough, but it works. Most of that logic can be common
for `stripping`, so we can expect more refactoring of that code to accommodate
both needs. However I wanted to keep this changesets "simple enough" and before
moving forward.

We also need to properly delete the older index/data/sidedata file, but this has
implication for streaming clone and transaction, so this will come later.
