pipeline: ipa: raspberrypi: Change Unicam timeout handling

Browse Source 
Add an explicit helper function setCameraTimeout() in the pipeline
handler to set the Unicam timeout value. This function is signalled from
the IPA to set up an appropriate timeout. This replaces the
maxSensorFrameLengthMs value parameter returned back from
IPARPi::start().

Adjust the timeout to be 5x the maximum frame duration reported by the
IPA.
