Before:

One could use the CMake variables `OGS_BUILD_PROCESSES` or
`OGS_BUILD_PROCESS_XYZ` but behavior was not consistent when switching
back and forth and using both methods. Also building multiple
processes via `OGS_BUILD_PROCESSES` was broken.

Changed:

- Removed `OGS_BUILD_PROCESS_XYZ` options.
- Use `OGS_BUILD_PROCESSES` with the following values:
  - ON  -> All processes are built.
  - OFF -> Disable all processes.
  - Select a single process by name, e.g. `TH2M`.
  - Give a ;-separated list of processes, e.g. '"THM;TH2M"'
- `OGS_BUILD_PROCESSES` can be set via ccmake or cmake-gui with a
  convenient dropdown, although setting multiple processes can only be
  done via the cli!
