Request new repo for QtPositioning

Name: qt/qtpositioning
Description: Qt Positioning module
Responsible persons: Alex Blasche (alexander.blasche@qt.io) and Ivan Solovev (ivan.solovev@qt.io)
 
The repo should be a full clone of qtlocation, including all tags and branches.
This is needed to ensure that QtLocation module development can be uncoupled from QtPositioning module packaging.
Currently enabling the building of the QtLocation module in the qtlocation.git repo cannot be done without automatically packaging QtLocation for the next Qt release.
