git: Move git-blame outside of git job queue (#43565)

Jakub Konka and Cole Miller created

We restructured `struct Repository` a bit so that it now stores a shared
task of `enum RepositoryState`. This way, we can now re-use it outside
of the git job queue when spawning a git job a standalone bg task. An
example here would be `git-blame` that does not require any file locks
and is not susceptible to git job ordering.

As a result of this change, loading (and modifying) a file that contains
a huge git history will no longer block other git operations on the repo
such as staging/unstaging/committing.

Release Notes:

- Improved overall git experience when loading buffers with massive git
history where they would block other git jobs from running (such as
staging/unstaging/commiting). Now, git-blame will run separately from
the git job queue on the side and the buffer with blame hints when
finished thus unblocking other git operations.
