Subject: Help: Document `cmake --build` as a separate command mode (#16093)

The `--build` mode was confusingly documented among other options,
falsely implying that it can be used anywhere on the command line.
Move the documentation to a dedicated section and clarify its usage
as s separate command line mode.
