As requested in #22104, moved the files and fixed other includes and build system. Moved files: - combine.hh - collection_mutation.hh - collection_mutation.cc - converting_mutation_partition_applier.hh - converting_mutation_partition_applier.cc - counters.hh - counters.cc - timestamp.hh Fixes: #22104 This is a cleanup, no need to backport Closes scylladb/scylladb#25085
