Guillaume Gomez 521c0ae1e8 Rollup merge of #33401 - GuillaumeGomez:index_indication, r=pnkfelix
Add rustc_on_unimplemented for Index implementation on slice

Reopening of #31071.

It also extends the possibility of `#[rustc_on_unimplemented]` by providing a small type filter in order to find the ones which corresponds the most.
