Split the Sensors QML plugin into a library and a plugin

The main changes:
- Introduction of new SensorsQuick library with private exports
- The original QML plugin loads this new library and does little else
- Renamed original 'sensors' plugin as 'declarative_sensors' to provide
  an idea what it relates to
- Renamed library headers as private "_p.h" and added "We mean it"
- Changed qmlRegister* calls to QML_ELEMENT macros
- Removed files that are generated in Qt6 (qmldir, plugins.qmltypes)

Task-number: QTBUG-92530
