libcamera: pipeline: simple: Add support for ST's DCMIPP

The STM32 contains a camera pipeline known as the DCMIPP (Digital
Camera-Memory Interface Pixel Processor) which receives data from a
parallel interface and dumps the post-processed data to memory. The
pipeline is capable of some processing in the form of downscaling
captured data through cropping or skipping the sensor's output.

The simple pipeline handler is quite capable of handling the DCMIPP
given its operation is handled entirely through configuring the pads
of a media graph, so add support for the driver to the pipeline's
supportedDevices array.
