Backport #39781 by @SudhanshuMatrix
## What
`parseGitDiffTreeLine` (`services/gitdiff/git_diff_tree.go`) read
`BasePath`/`HeadPath` straight from `git diff-tree --raw` output without
undoing git's C-quoting, unlike its sibling `parseLsTreeLine`
(`modules/git/parse.go`), which already does this with
`strconv.Unquote`.
This fix applies the same unquoting to both paths in the diff-tree
parser.
## Why
With the default `core.quotePath=true`, git C-quotes **any path
containing a non-ASCII byte** — not just tabs/newlines/backslashes. That
means any file with a CJK, Cyrillic, accented-Latin, or emoji name gets
octal-escaped, e.g.:
```
:100644 100644 b6fc4c6... 04fea06... M "\346\227\245\346\234\254\350\252\236.txt"
```
(`日本語.txt`, confirmed against real `git diff-tree --raw` output)
`GetDiffTree` backs the file-tree sidebar on the commit, compare, and
pull request diff pages (`routers/web/repo/commit.go`, `compare.go`,
`pull.go`). Without unquoting, any such file shows its mangled, escaped
name instead of the real one, and the wrong path can throw off
jump-to-file and viewed-file-state behavior that key off the path.

before: gitrepo vs git packages
after: git package fully handle all git operations
by the way, use `WithRepo(repo)` instead of `WithDir(repo.Path)` to hide
path details.
benefits:
1. remove all unnecessary wrappers, developers no need to struggle with
"which package should be used"
2. simplify code, RepositoryFacade can (will) be used everywhere, all
"path" details are (will be) hidden
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"`

Refactor Git command functions to use WithXXX methods instead of
exposing RunOpts.
This change simplifies reuse across gitrepo and improves consistency,
encapsulation, and maintainability of command options.

* Implemented calling git diff-tree
* Ensures wrapper function is called with valid arguments
* Parses output into go struct, using strong typing when possible
