libcamera: pipeline: Introduce skeleton Vivid Pipeline
Provide all of the skeleton stubs to succesfully compile
and register a new Pipeline Handler for the Vivid test device.
Meson must be reconfigured to ensure that this pipeline handler is
included in the selected pipelines configuration, and after building, we
can test that the PipelineHandler is successfully registered by listing
the cameras on the system with LIBCAMERA_LOG_LEVELS enabled:
"""
LIBCAMERA_LOG_LEVELS=Pipeline:0 ./build-vivid/src/cam/cam -l
[230:30:03.624102821] [2867886] DEBUG Pipeline pipeline_handler.cpp:680 Registered pipeline handler "PipelineHandlerVivid"
Available cameras:
