libcamera: ipa_manager: implement class for managing IPA modules

IPAManager is a class that will search in given directories for IPA modules, and will load them into a list. It also provides an interface for pipeline handlers to acquire an IPA. A meson build file for the IPAs is added, which also specifies a hard-coded path for where to load the IPAs from in the installation directory. More paths can be specified with the environment variable LIBCAMERA_IPA_MODULE_PATH, with the same syntax as the regular PATH environment variable. Make the test framework set this environment variable. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
