Make unresolvable App fails independently

[davidlatwe]

Problem

If an application package is missing or it's dependency is missing, will raise PackageFamilyNotFoundError or PackageNotFoundError and failling whole profile.

Proposal

I think it could be more atomic, handling application that have missing packages, and continue to resolve other.

Additional Improvement

Features like, launching application tool, diagnose environment, graphing resolved context,.. will be blocked if selected application is broken (resolve failed).

Implementation details

• Profile package will be resolved solely at first, then resolve with each app if profile itself is solvable.
• Some of the checkBox widgets which created with qargparse.py were emitting value changed signal twice in one click, which may trigger data model reset twice and leads to crash. E.g. "Use Development Pakcages" check box. Updating qargparse.py fixed the issue.
• Two controller state were added, appfailed and appok, for triggering feature block/unblock.
• Added more tests with a bit improvement. Running tests on Azure DevOps are much stable now, but there are still have a little chance occurring Segmentation fault on Ubuntu. I have got Ubuntu installed on my Windows with WSL2 and running tests locally, still not able to reproduce that Segmentation fault. :/

Currently, when that happened, press the "Re-Run" in PR's "Checks" page to give it another shot. 🤕

If this gets merged, I think we should bump minor version number.
Update: Ignore that, I'll just make a separate release.
