setup: introduce the discover_git_directory() function

We modified the setup_git_directory_gently_1() function earlier to make
it possible to discover the GIT_DIR without changing global state.

However, it is still a bit cumbersome to use if you only need to figure
out the (possibly absolute) path of the .git/ directory. Let's just
provide a convenient wrapper function with an easier signature that
*just* discovers the .git/ directory.

We will use it in a subsequent patch to fix the early config.
