WIP: Introduce `message(VERBOSE ...)`

Proposed implementation for #18943 (closed)

However, I've faced w/ a difficulty to add CMAKE_VERBOSE_LEVEL variable: I just didn't get (yet) how to do that at the very beginning stage (when CLI args get parsed). So, any help would be appreciated! (ping @brad.king or @craig.scott %)

PS. The other things in my TODO list are to add docs and a release note...

@zaufi thanks. Please open an issue to describe the proposal, and then reference that from the MR description instead. That way we have a place to point related issues in the future.
