CMake: Add CMakeConfigurationKitInformation

Add CMakeConfigurationKitInformation and supporting classes.

This KitInformation can hold CMake settings that are to be applied
for all configurations when this kit is used. It contains e.g.
the Qt version and toolchain configured in the kit by default, but
can be extended to hold more.

The UI will warn if the toolchain or Qt version set up in CMake
does not match up with those used by the Kit, but it will allow
the user to proceed.
