Verbose message about CMake preset variables

Can we move the messages about cmake preset variables to the VERBOSE log level? They are noisy and for scenarios where cmake is repeatedly invoked with the --preset option for the same directory, they are a distraction that the user cannot remove.

Alternatively, we could consider only printing a message for those variables that were newly added or that modified an existing value. Preset handling might occur too early to be able to do that easily though.

While I do like the preset variable print out on configure, I can also see that it would be most consistent to have this be at Verbose log level.
