Fix bp2build for cc_aidl_library to use LabelListAttribute.Partition

Using LabelListAttribute.Partition instead of Includes ensures the configuration axes are taken into account when iterating through the AIDL srcs and filegroups

This CI should not have any effect on the already converted modules and bp2build tests.
