Rollup merge of #109443 - GuillaumeGomez:doc-primitive-hard-error, r=notriddle

Move `doc(primitive)` future incompat warning to `invalid_doc_attributes`

Fixes #88070.

It's been a while since this was turned into a "future incompatible lint" so I think we can now turn it into a hard error without problem.
