refactor: decouple git.Repository(ctx) from git.Commit & git.Tree (#38464)

Browse Source 
1. Storing "ctx" in a long-living object is wrong
2. Make the commit & tree cacheable (for the future performance
optimization)
3. Also fix some bad designs like `// FIXME: bad design, this field can
be nil if the commit is from "last commit cache"`

* #33893
