cmake-gui: Add options to control warning messages

Create a new dialog window for the cmake-gui that provides controls for
setting the state of suppression of developer and deprecated warning
messages.  This replaces the previous single checkbox for setting the
state of suppression of developer warnings.

Added a note for the new functionality to the release notes.
