Unfortunately, we can't completely remove the ctx from git.Repository,
because the CatFileBatch still heavily depends on a parent context.
If we remove the Repository ctx, the CatFileBatch will become a mess and
create a lot of unnecessary git processes.

* After: only a few (no duplicate cat-file)
Replace #34651 and address more problems including fix framework bugs and changing to QueryInfo and QueryContent calls.
