Allow both explicit and elided lifetimes in the same impl header #54458
While still prohibiting explicit and in-band in the same header.
As usual, I don't know the broader context of the code I'm changing, so please let me know whatever I can do better.
Pre-existing test that mixing explicit and in-band remains an error: https://github.com/rust-lang/rust/blob/master/src/test/ui/in-band-lifetimes/E0688.rs
