Garbage collected sstables created during incremental compaction are deleted only at the end of the compaction, which increases the memory footprint. This is inefficient, especially considering that the related input sstables are released regularly during compaction. This commit implements incremental release of GC sstables after each output sstable is sealed. Unlike regular input sstables, GC sstables use a different exhaustion predicate: a GC sstable is only released when its token range no longer overlaps with any remaining input sstable. This is because GC sstables hold tombstones that may shadow data in still-alive overlapping input sstables; releasing them prematurely would cause data resurrection. Fixes #5563 Closes scylladb/scylladb#28984

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
