libcamera: Add debug printouts
Add a few debug printouts that help follow the library intialization
process: what pipeline handlers are registered, what media devices are
created, and which pipeline manager gets matches with the current
system.
The resulting output is the following, on IPU3 devices:
DBG pipeline_handler.cpp:119 Pipeline handler: "PipeHandlerVimc" registered
DBG pipeline_handler.cpp:119 Pipeline handler: "PipelineHandlerIPU3" registered
DBG device_enumerator.cpp:214 New media device: ipu3-imgu created from: /dev/media0
DBG device_enumerator.cpp:214 New media device: ipu3-cio2 created from: /dev/media1
DBG device_enumerator.cpp:255 Succesfull match for media device: ipu3-cio2
DBG device_enumerator.cpp:255 Succesfull match for media device: ipu3-imgu
DBG pipeline_handler.cpp:150 Pipeline handler: "PipelineHandlerIPU3" matched
