cmake: follow-up zephyr_dt_preprocess() fixes
Follow-up fixes to 64c7f5022962444e86d88d5cf7c6299a3b2861ec
("cmake: extensions: fix zephyr_dt_preprocess() CPP handling") that
weren't urgent enough for the hotfix, or didn't get noticed:
- error out on missing CPP argument again (this regression was
introduced in 64c7f50229)
- use a UNIX manpage style argument arity format (formatting issues
were present when the function was introduced)
- fix incorrect signature comment: the CPP arguments are the
preprocessor and its arguments, not CMAKE_DTS_PREPROCESSOR
(this was present when the function was introduced)
