Fork p4-fusion package and update in server + gitserver (#57762)

Combine #57751 and #57756 to fork p4-fusion into a separate package, and update relevant images.

We've forked the tool and are now ready to try some of the fixes out in a more production enviroment, so bundling this temporarily from a specific commit from the fork repo.

Next up, I'll open a PR to use the newly generated base image in bazel and add the new --noBaseCommit flag to the perforce syncer.
