address clippy formatting nits
- int_log10.rs: change top level doc comments to outer
- collect.rs: remove empty line after doc comment
- clippy fix: markdown indentation for indented items after line break: a markdown list item continued over multiples lines, but those following lines which are part of the same item are not indented
- clippy fix: bound in one place: when there is a bound in angle brackets and another bound on the same variable in a where clause

Constify `Index` traits
tracking issue: rust-lang/rust#143775
the `SliceIndex` trait cannot be implemented by users as it is sealed. While it would be useful for the `get` method on slices, it seems weird to have a feature gate for that that isn't also gating index syntax at the same time, so I put them under the same feature gate.
