Migrate to the gradle.settings approach when generating Android projectsHEADdev

This approach is more flexible and modernizes the gradle project
structure for Qt apps. We now try to reproduce the CMake Android project
structure of user applications, in the modern Android project
structure described here: https://developer.android.com/build

The new structure using the module based application build and unlocks
the support for the use of dynamic features and Android libraries(aar).

All gradle-related rules are generated by CMake and androiddeployqt is
used in the auxiliary mode only(--aux-mode option). Update gradle
templates.

To opt-in the modern deployment use the QT_ANDROID_MODERN_BUNDLE
variable.
