Bart 3a172301ce chore: Remove unity builds (#6300)
Unity builds were intended to speed up builds, by bundling multiple files into compilation units. However, now that ccache is available on all platforms, there is no need for unity builds anymore, as ccache stores compiled individual build objects for reuse. This change therefore removes the ability to make unity builds.

"""
Generate a strategy matrix for GitHub Actions CI.
On each PR commit we will build a selection of Debian, RHEL, Ubuntu, MacOS, and
Windows configurations, while upon merge into the develop or release branches,
we will build all configurations, and test most of them.
We will further set additional CMake arguments as follows:
- All builds will have the `tests`, `werr`, and `xrpld` options.
- All builds will have the `wextra` option except for GCC 12 and Clang 16.
- All release builds will have the `assert` option.
- Certain Debian Bookworm configurations will change the reference fee, enable
codecov, and enable voidstar in PRs.
