rustc: Fix procedural macros generating lifetime tokens This commit fixes an accidental regression from #50473 where lifetime tokens produced by procedural macros ended up getting lost in translation in the compiler and not actually producing parseable code. The issue lies in the fact that a lifetime's `Ident` is prefixed with `'`. The `glue` implementation for gluing joint tokens together forgot to take this into account so the lifetime inside of `Ident` was missing the leading tick! The `glue` implementation here is updated to create a new `Symbol` in these situations to manufacture a new `Ident` with a leading tick to ensure it parses correctly.
