Spike the possibility of fully moving androiddeployqt under CMake

Before deciding how to proceed with any refactoring work for androiddeployqt, it's beneficial to check if all of its functionality can be done under Qt CMake. If that's possible, then it makes sense to do that to have one less tool to worry about. That also might be useful for IDE like Qt Creator where it wouldn't care about the underlying layers of the deployment but it could simply rely on CMake to do all build/deployment steps.

And that potentially can help make the deployment steps more friendly with other dev environments, like building Qt apps from Android Studio.
