libcamera: converter: Replace usage of stream index by Stream pointer

The converter interface uses the unsigned int output stream index to map
to the output frame buffers. This is cumbersome to implement new
converters because one has to keep around additional book keeping
to track the streams with their correct indexes.

The v4l2_converter_m2m and simple pipeline handler are adapted to
use the new interface. This work roped in software ISP as well,
which also seems to use indexes (although it doesn't implement converter
interface) because of a common conversionQueue_ queue used for
converter_ and swIsp_.

The logPrefix is no longer able to generate an index from a stream, and
is updated to be more expressive by reporting the stream configuration
instead, for example, reporting "1920x1080-MJPEG" in place of
"stream0".
