chore: Restore unity builds (#6328)

In certain cases, such as when modifying headers used by many compilation units, performing a unity build is slower than when performing a regular build with `ccache` enabled. There is also a benefit to a unity build in that it can detect things such as macro redefinitions within the group of files that are compiled together as a unit. This change therefore restores the ability to perform unity builds. However, instead of running every configuration with and without unity enabled, it is now only enabled for a single configuration to maintain lower computational use.

As part of restoring the code, it became clear that currently two configurations have coverage enabled, since the check doesn't focus specifically on Debian Bookworm so it also applies to Debian Trixie. This has been fixed too in this change.
