Ævar Arnfjörð Bjarmason 1d232d38bd ls-tree: test for the regression in 9c4d58ff2c 
Add a test for the regression introduced in my 9c4d58ff2c (ls-tree:
split up "fast path" callbacks, 2022-03-23) and fixed in
350296cc78 (ls-tree: `-l` should not imply recursive listing,
2022-04-04), and test for the test of ls-tree option/mode combinations
to make sure we don't have other blind spots.

The setup for these tests can be shared with those added in the
1041d58b4d (Merge branch 'tl/ls-tree-oid-only', 2022-04-04) topic, so
let's create a new t/lib-t3100.sh to help them share data.

The existing tests in "t3104-ls-tree-format.sh" didn't deal with a
submodule, which they'll now encounter with as the
setup_basic_ls_tree_data() sets one up.

This extensive testing should give us confidence that there were no
further regressions in this area. The lack of testing was noted back
in [1], but unfortunately we didn't cover that blind-spot before
9c4d58ff2c.
