libcamera: camera_manager: Add environment variable to order pipelines match
To match the enumerated media devices, each registered pipeline handler
is used in no specific order. It is a limitation when several pipelines
can match the devices, and user has to select a specific pipeline.
For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is
created to give the option to define an ordered list of pipelines to
match on.
LIBCAMERA_PIPELINES_MATCH_LIST="<name1>[,<name2>[,<name3>...]]]"
Example:
LIBCAMERA_PIPELINES_MATCH_LIST="rkisp1,simple"
