Add `avb_custom_vbmeta_images_partition_list` to misc_info.txt

Make generates this from `BOARD_AVB_VBMETA_CUSTOM_PARTITIONS`. To
generate this in Soong, a new Filesytem_partition_type is added to
vbmeta modules. For the chained vbmeta partitions for cuttlefish, this
will be
- system
- vendor
- system_dlkm
- vendor_dlkm

android_device will query this information from its vbmeta partitions,
and filter out system and vendor.
