We have increased our platform coverage now through a number of pipeline
handlers, and also through pipeline handlers such as the Simple pipeline
handler which can support multiple platforms.

The ISI can be managed by both a dedicated pipeline or the Simple
pipeline, and on the NXP i.MX8MP a camera could be connected to either
the ISP or the ISI.

Thus there are three separate pipeline handlers which might manage and
control the same physically connected camera depending upon the overall
software configuration (both DT and libcamera builds).

Introduce a new camera property as the pipeline handler name and
automatically set the property value when constructing a camera.

This helps when working on a platform or debugging remote platforms to
be able to quickly identify the overall configuration when working with
software which reports the information such as camshark.
