Following patches support reporting mounting rotation of the
camera sensor in libcamerasrc. These are now reported as GstDevice
properties.

Patch 1/2 provides a public helper to derive a std::string for 
Orientation enum.

Patch 2/2 plumbs the libcamera's 'property::Rotation' in libcamerasrc.
It provides a human readable string in case the rotation is in
multiple of 90, otherwise, simply reports the value of rotation
property as a string.
