[PATCH v2] ls-tree: test for the regression in 9c4d58ff2c3

In-Reply-To
<patch-1.1-0fdfec624eb-20220531T171908Z-avarab@gmail.com>

Add a test for the regression introduced in my 9c4d58ff2c3 (ls-tree: split up "fast path" callbacks, 2022-03-23) and fixed in 350296cc789 (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 1041d58b4d9 (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 9c4d58ff2c3.

Fix a quoting issue in v1 that made CI fail, now passes: https://github.com/avar/git/tree/avar/ls-tree-rewrite-regression-test-2

I usually check the CI before submitting, but I don't know how that slipped through in this case, sorry, and thanks for the quick review/diagnosis.
