ipa: raspberrypi: Pass the maximum allowable shutter speed into the AGC

Browse source 
In order to provide an optimal split between shutter speed and gain, the
AGC must know the maximum allowable shutter speed, as limited by the
maximum frame duration (either application provided or the default).

Add a new API function, SetMaxShutter, to the AgcAlgorithm class. The
IPA provides the maximum shutter speed for AGC calculations. This
applies to both the manual and auto AGC modes.
