We already have a couple tests for `add` with SKIP_WORKTREE entries in
t7012, but these only cover the most basic scenarios. As we will be
changing how `add` deals with sparse paths in the subsequent commits,
let's move these two tests to their own file and add more test cases
for different `add` options and situations. This also demonstrates two
options that don't currently respect SKIP_WORKTREE entries: `--chmod`
and `--renormalize`.

These are good tests. I will adapt these for my sparse-index
series to ensure 'git add' works correctly in that environment.

Thanks,
