and override it in table::table_state to get the tombstone_gc_state
from the table's compaction_manager.
It is going to be used in the next patched to pass the gc state
from the compaction_strategy down to sstables and compaction.
table_state_for_test was modified to just keep a null
tombstone_gc_state.
