Description
We should have an assist that unelides lifetimes in a function, inserting them all and having snippets pre-selecting them. Given we lack proper support of lifetimes in hir and mapping them back this is currently a bit trickly to implement / needs to be fully syntax based. So probably rather annoying to implement currently

Research direction
Start by investigating rust-analyzer's lifetime support in HIR and how assists map syntax, since the issue identifies these as the main implementation constraints. Done means an assist can unelide all lifetimes in a function and provide snippets that pre-select the inserted lifetimes.
