Faster compilation of bevy_diagnostic (#1235)
* Remove AHashExt

There is little benefit of Hash*::new() over Hash*::default(), but it
does require more code that needs to be duplicated for every Hash* in
bevy_utils. It may also slightly increase compile times.

* Add StableHash* to bevy_utils

* Use StableHashMap instead of HashMap + BTreeSet for diagnostics

This is a significant reduction in the release mode compile times of
bevy_diagnostics
