Reduce GUI compile time by building a GUI library (#7412)

* Call ensure_in_venv before all imports

* Create `gui` lib and link to `synergy` and test bins

* Move GUI IPC code to GUI lib

* Improve `AppConfig` members and change `minimizeOnClose` to `closeToTray`

* Group getters and setters

* Add missing `m_CloseToTray` load

* Fixed lint issue

* Add TODO comment for main window integ test

* Remove redundant comments and add override

* Remove dead code

* Update ChangeLog

* Fixed activation related compile errors

* Disable concurrency cancel jobs

* Disable fail-fast for matrix
