Kamil Braun 2606c190af cql3: statements: pass migration_manager& explicitly to prepare_schema_mutations
We want to stop relying on `qp.get_migration_manager()`, so we can make
the function private in the future. This in turn is a prerequisite for
splitting `query_processor` initialization into two phases, where the
first phase will only allow local queries (and won't require
`migration_manager`).
