Suppress new Jammy warnings

[mjcarroll]

• Test files should have the .cc extension, CMake is more strict now b4c2a46
• QML wants explicit functions now rather than implicit properties: 3b0ad2f
• There is a whole bunch of log spew related to the QML engine, there was a related bug: https://bugreports.qt.io/browse/QTBUG-81247.
  • It appears to be largely a sequencing error, and the QML engine needs to be stopped/destroyed first to stop binding reevaluation.
  • I broke apart some of the Application plugin tests to try to narrow down where the remaining warnings were coming from. I managed to get to the TestBadInheritancePlugin, but couldn't determine what is wrong with that particular test.

hi @mjcarroll , before merge this PR, it has many QML warnings while quit from gazebo gui.

MainWindow_TEST is failing: https://build.osrfoundation.org/job/ignition_gui-ci-pr_any-ubuntu_auto-amd64/2027/testReport/(root)/MainWindowTest/ApplyConfig/

We can ignore Focal builds for Harmonic.

[azeey]

There are still some warnings on Jammy. Was this meant to address all warnings?

[mjcarroll]

Was this meant to address all warnings?

Just greatly reduce unfortunately, there is still a Qt sequencing issue that I haven't been able to resolve those last few.

[iche033]

I found that if you change the TestBadInheritancePlugin to load a plugin that inherits something other than MainWindow, e.g. Dialog, the warnings for that test are gone. I think the idea behind that test remains the same, bad inheritance, but just inheriting from a different class.

MainWindow_TEST is failing

So it's now only failing on focal, which we aren't targeting with main at this point. I think this is good to go.
