Add //visibility:any_partition

When we convert the partitions to be built with soong, there will
likely be separate partition modules per product. This means that a
lot of installable modules will have to be visible to a lot of
partitions. To make this easier, add the //visibility:any_partition
visibility spec, which allows the module to be used from any module
of type android_filesystem or android_system_image.
