Add slot suffix to DAP ops

If device supports both A/B and non-A/B, when applying a
non-A/B package, add current slot suffix and apply the update
to the partition at current slot.

This includes:
- (un)map_partition in edify script. For example,
  map_partition("system") will automatically append slot suffix
  to "system" before calling CreateLogicalPartition.
- All operations in dynamic_partitions_op_list. For example,
  add foo group_foo
  will automatically append slot suffix to foo and group_foo
  before editing the super partition metadata.

Test: apply update
