fix: use commondir to resolve git directory in worktrees (#13045)
This PR fixes git revision detection in worktrees where the worktree's
gitdir path passes through another git repository.

The vendored `GetGitRevisionDescription.cmake` module detects worktrees
and then calls `_git_find_closest_git_dir` to find the shared git
directory by walking up the filesystem looking for a `.git` entry. This
fails when the worktree's gitdir is stored inside another git repository
(e.g. when the project is a git submodule whose objects live at
`~/.git/modules/...` and `~` is itself a git repo) — the walk finds the
wrong `.git`.

The fix reads the `commondir` file that git places in every worktree's
gitdir, which directly points to the shared git object directory. Falls
back to the old filesystem walk if `commondir` doesn't exist (shouldn't
happen with any modern git, but safe to keep).
