Rollup merge of #64121 - timvermeulen:iter_step_by_internal, r=scottmcm
Override `StepBy::{try_fold, try_rfold}`
Previous PR: https://github.com/rust-lang/rust/pull/51435
The previous PR was closed in favor of https://github.com/rust-lang/rust/pull/51601, which was later reverted. I don't think these implementations will make it harder to specialize `StepBy<Range<_>>` later, so we should be able to land this without any consequences.
This should fix https://github.com/rust-lang/rust/issues/57517 – in my benchmarks `iter` and `iter.step_by(1)` now perform equally well, provided internal iteration is used.
