QtSensors initial cmake support

This commit introduces the bare minimum cmake support that should
unblock the CI and allow further verification and development on most
platforms: macOS, Linux, Win, iOS and Android.

Some clarifications:
* The support for sensorfw backend is very preliminary and can
  be enabled later if needed (no Qt6 version of the sensorfw).
* The simulator backend is dropped as obsolete / unnecessary.
* Three examples are currently commented out and shall be ported with
  a later commit.

Task-number: QTBUG-92502
