ipa: raspberrypi: Limit the calculated vblank based on the sensor mode
The existing framerate/vblank calculations did not account for the
sensor mode limits. This commit extracts vblank limits from the sensor
v4l2 controls, and stores it in the camera modes structure.
Exposure and vblank value calculations now use values clamped to the
sensor mode limits. The libcamera::controls::FrameDurations metadata
return values now reflect the minimum and maximum after clamping.
