Move qmake specific part to qmake plugin, generalize android support

- Split up androiddeployqt into two steps: One building the apk,
  and one deploying it to the device.
- The build apk step base class AndroidBuildApkStep is ihneritaged by
  the qmake specific class QmakeAndroidBuildApkStep.
- The deployment step is still called androiddeployqt
- Move all qmake specific code to the qmakeprojectmanager plguin
- Flip the depencency between the android and qmake plugin, now
  the qmake plugin depends on the android plugin, implementing
  a interface the android plugin provides.

- Note: This removes the debug deployment for now.
