Android: Add option to set the build-tools version in project settings

Allow QC to directly set the build-tools version for the project.
Such setting could be in qmake/cmake, however, ideally this value
should be the latest available version, and doesn't need to be written
to the project file. Thus, it is convenient to have this selectable
from QC UI for convience, while developing.

Apart from the first reason for avoiding writing this into the project
file, there is QC limitation which doesn't allow writing such value
to CMake project file.
