FindCUDA: Improve deprecation guidance wording

Simplified the text regarding adding sources to be more general as there's also
target_sources().

Improved the wording for FindCUDAToolkit to be more explicit of its usecase and
avoid using "superseded" since the common usecase of FindCUDA was superseded by
the language support.

Wording suggestions incopropated from discussion on #22203.
