ipa: ipu3: set frameContext before controls
The AGC frame context needs to be initialised correctly for the first iteration. Until now, the IPA uses the minimum exposure and gain values and caches those in local variables. In order to give the sensor limits to AGC, create a new structure in IPASessionConfiguration. Store the exposure in time (and not line duration) and the analogue gain after CameraSensorHelper conversion. Set the gain and exposure appropriately to the current values known to the IPA and remove the setting of exposure and gain in IPAIPU3 as those are now fully controlled by IPU3Agc.
