Remove git dependency from Android version code calculation

- Replaces 'git log --oneline | wc -l' with pure qmake logic
- Dev builds use fixed version code 1 (not distributed)
- Release/alpha/beta/rc builds compute version code from VERSION string
- Encoding: major(2) + minor(4) + patch(4) + type(1) + num(1)
- Works on all platforms (Windows, macOS, Linux) without git
- Works with source tarballs
- Fixes issue jamulussoftware#3087
