pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi code
Split the Raspberry Pi pipeline handler and IPA source code into common
and VC4/BCM2835 specific file structures.
For the pipeline handler, the common code files now live in
src/libcamera/pipeline/rpi/common/
and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/.
For the IPA, the common code files now live in
src/ipa/rpi/{cam_helper,controller}/
and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the
camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/.
To build the pipeline and IPA, the meson configuration options have now
changed from "raspberrypi" to "rpi/vc4":
meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4
