path.c: add git_common_path() and strbuf_git_common_path()
These are mostly convenient functions to reduce code duplication. Most of the time, we should be able to get by with git_path() which handles $GIT_COMMON_DIR internally. However there are a few cases where we need to construct paths manually, for example some paths from a specific worktree. These functions will enable that.
