libcamera: camera_sensor: Adjust properties::Rotation

Browse Source 
As the CameraSensor::validateTransform() function compensate
for the sensor's mounting rotation, the properties::Rotation value
should be adjusted to make sure application that receive already
"corrected" images do not get confused by Rotation still reporting
a value.

Howerver, as an image sensor can only compensate rotations by applying
H/V flips, only correct Rotation when the mounting rotation is 180
degrees.
