Get Clippy clean for Rust 1.80 and run it on CI

[alamb]

Is your feature request related to a problem or challenge?

A new Rust version was released that causes CI to fail -- see #11651

@findepi made a PR to pin CI to use Rust 1.79 while we work out the clippy failures: #11655

We should remove the wokaround and use the latest rust once we have sorted out clippy

Describe the solution you'd like

Remove the workaround file and use the latest rust again

Note I believe @nrc has fixed some of these already in #11467, but we got stuck there on tests that only failed once we properly passed through hash_collisions

#11654 includes #11467 and passes clippy 1.80 locally
