Summary: Greatly reduced the not-quite-copy-paste giant parameter lists of rocksdb::NewTableBuilder, rocksdb::BuildTable, BlockBasedTableBuilder::Rep ctor, and BlockBasedTableBuilder ctor. Moved weird separate parameter `uint32_t column_family_id` of TableFactory::NewTableBuilder into TableBuilderOptions. Re-ordered parameters to TableBuilderOptions ctor, so that `uint64_t target_file_size` is not randomly placed between uint64_t timestamps (was easy to mix up). Replaced a couple of fields of BlockBasedTableBuilder::Rep with a FilterBuildingContext. The motivation for this change is making it easier to pass along more data into new fields in FilterBuildingContext (follow-up PR).
