fix: Don't include modules via a macro

[nicklan]

What changes are proposed in this pull request?

Turns out rustfmt won't format module files that are included via a macro. See here.

This meant things like log_segment.rs that were included via internal_mod! were not getting formatted.

This removes that macro and just uses the "double include" gated by feature flags, which rustfmt can handle.

How was this change tested?

Making sure that miss-formatted code in the effected modules is now formatted when running cargo fmt.

No worries, it's a really odd edge case

(removing breaking_change label as I don't believe this is actually a breaking change. it just sees we removed an exported macro, but no one is using it)
