pipeline: raspberrypi: Read config parameters from a file
Add the ability to read the platform configuration parameters from a
config file provided by the user through the LIBCAMERA_RPI_CONFIG_FILE
environment variable. Use the PipelineHandler::configurationFile()
helper to determine the full path of the file.
Provide an example configuration file named example.yaml. Currently two
parameters are available through the json file:
"min_unicam_buffers" The minimum number of internal Unicam buffers to
allocate.
"min_total_unicam_buffers" The minimum number of internal + external
Unicam buffers that must be allocated.
