In `tools/build.py`: - For the sake of readability, group CLI arguments as general build options, options to control the building of components, and component-specific options. - To prevent duplications, remove the defaults from those CLI arguments that correspond to CMake options and have defaults in any of the CMakeLists. Should any of the defaults change, they will have to be changed at a single place only. (Those options that are not set on the command line of `tools/build.py` are not passed as options to `cmake` either.) - Convert `--unittests` and `--doctests` to ON/OFF options like the rest of the component switches. - Touch on some of the help messages of the CLI arguments. Other changes: - The change in `--unittests` and `--doctests` is a slightly CLI- breaking change of `tools/build.py`. Thus, follow up on this in `tools/run-tests.py`. - Move `ENABLE_ALL_IN_ONE` into `jerry-core` as it is not a general option but specific to that component. - Remove the forcing of `ENABLE_ALL_IN_ONE` for some compilers/ platforms as it is still an option, not a hard requirement.
