crates: move all sub-crates into crates/ directory

I should have just done this from the start. I hate doing these kinds of
moves because it fucks up revision history. But if I'm going to be
adding `jiff-icu`, `jiff-chrono`, `jiff-sqlx` and so on, then I really
think we need a sub-directory.

I'm keeping Jiff proper in `src/` though.
