Benny Halevy 1f7faeef57 sstables: populate LargeDataRecords from writer ...

During compaction (SSTable writing), maintain bounded min-heaps (one per
large_data_type) that collect the top-N above-threshold records.  On
stream end, drain all five heaps into a single LargeDataRecords array
and write it into the SSTable's scylla metadata component.

Five separate heaps are used:
- partition_size, row_size, cell_size: ordered by value (size bytes)
- rows_in_partition, elements_in_collection: ordered by elements_count

A new config option 'compaction_large_data_records_per_sstable' (default
10) controls the maximum number of records kept per type.
