When a compaction strategy uses garbage collected sstables to track expired tombstones, do not use complete partition estimates for them, instead, use a fraction of it based on the droppable tombstone ratio estimate. Fixes scylladb#18283 Signed-off-by: Lakshmi Narayanan Sreethar <lakshmi.sreethar@scylladb.com> Closes scylladb#18465 (cherry picked from commit d39adf6)
