build: cmake cleanup (#22251)

- Remove unused code
- Use consistent casing. Variable names such as LibLuV_LIBRARIES is
  needlessly jarring, even if the name might be technically correct.
- Use title casing for packages. find_package(unibilium) requires the
  find_module to be named "Findunibilium.cmake", which makes it harder
  to spot when scanning the files. Instead, use "Unibilium".
