generic: Add some tests around journal replay/recoveryloop

Hello,

Sending v2 with tests/ext4/ converted to tests/generic/
(although I had not received any review comments on v1).
It seems all of the tests which I had sent in v1 are not ext4 specific anyways. So in v2, I have made those into tests/generic/.

These are some of the tests which when tested with ext4 fast_commit feature w/o kernel fixes, could cause tests failures and/or KASAN bug (generic/486).

I gave these tests a run with default xfs, btrfs and f2fs configs (along with ext4). No surprises observed.

[v1]: https://lore.kernel.org/all/[email protected]/
