bundlerepo: use _cacheabletip mechanism in bundlerepo

Instead of preventing any cache write we allow writing cache for all content of
the original repo.

The motivation for this change is to drop the custom _writebranchcache of
bundlerepo to help extraction of the branchmap logic out of localrepo.
