Loading schemas of views and indexes was not supported, with either `--schema-file`, or when loading schema from schema sstables. This PR addresses both: * When loading schema from CQL (file), `CREATE MATERIALIZED VIEW` and `CREATE INDEX` statements are now also processed correctly. * When loading schema from schema tables, `system_schema.views` is also processed, when the table has no corresponding entry in `system_schema.tables`. Tests are also added. Fixes: #16492 Closes scylladb/scylladb#16517 * github.com:scylladb/scylladb: test/cql-pytest: test_tools.py: add schema-loading tests for MV/SI test/cql-pytest: test_tools.py: extract some fixture logic to functions test/cql-pytest: test_tools.py: extract common schema-loading facilities into base-class tools/schema_loader: load_schema_from_schema_tables(): add support for MV/SI schemas tools/schema_loader: load_one_schema_from_file(): add support for view/index schemas test/boost/schema_loader_test: add test for mvs and indexes tools/schema_loader: load_schemas(): implement parsing views/indexes from CQL replica/database: extract existing_index_names and get_available_index_name tools/schema_loader: make real_db.tables the only source of truth on existing tables tools/schema_loader: table(): store const keyspace& tools/schema_loader: make database,keyspace,table non-movable cql3/statements/create_index_statement: build_index_schema(): include index metadata in returned value cql3/statements/create_index_statement: make build_index_schema() public cql3/statements/create_index_statement: relax some method's dependence on qp cql3/statements/create_view_statement: make prepare_view() public
