This patch enables integrity check in 'create_stream_sources()' by introducing a new 'sstable_data_stream_source_impl' class for handling the Data component of SSTables. The new implementation uses 'sstable::data_stream()' with 'integrity_check::yes' instead of the raw input_stream. These additional checks require reading the digest and CRC components from disk, which may introduce some I/O overhead. For uncompressed SSTables, this involves loading and computing checksums and digest from the data. For compressed SSTables - where checksums are already embedded - the cost comes from reading, calculating and verifying the diges. New test cases were added to verify that the integrity checks work correctly, detecting both data and digest mismatches. Backport is not required, since it is a new feature Fixes #21776 Closes scylladb/scylladb#26702 * github.com:scylladb/scylladb: file_stream_test: add sstable file streaming integrity verification test cases streaming: prioritize sender-side errors in tablet_stream_files sstables: enable integrity check for data file streaming sstables: Add compressed raw streaming support sstables: Allow to read digest and checksum from user provided file instance sstables: add overload of data_stream() to accept custom file_input_stream_options
