Use F14FastMap for protocol::Object::members

Summary: Box with cpp.Ref for protocol::Object::members and use folly::F14FastMap instead. Improve read ~2x and write ~20% for ComplexStruct compared to the original before D45419589 ``` // before ============================================================================================= fbcode/thrift/lib/cpp2/test/ProtocolBench.cpp relative time/iter iters/s serialized_size ============================================================================================= ObjectBinaryProtocol_write_LargeMapInt 29.20ms 34.24 NaN ObjectBinaryProtocol_read_LargeMapInt 289.67ms 3.45 8000010 ObjectBinaryProtocol_write_NestedMap 2.86ms 349.47 NaN ObjectBinaryProtocol_read_NestedMap 26.76ms 37.37 955550 ObjectBinaryProtocol_write_ComplexStruct 148.94ms 6.71 NaN ObjectBinaryProtocol_read_ComplexStruct 1.07s 935.68m 59006614 ObjectCompactProtocol_write_LargeMapInt 31.28ms 31.97 NaN ObjectCompactProtocol_read_LargeMapInt 294.95ms 3.39 7928804 ObjectCompactProtocol_write_NestedMap 3.01ms 332.02 NaN ObjectCompactProtocol_read_NestedMap 29.00ms 34.48 649304 ObjectCompactProtocol_write_ComplexStruct 149.92ms 6.67 NaN ObjectCompactProtocol_read_ComplexStruct 1.13s 885.15m 38637969 ============================================================================================= ``` ``` // after ============================================================================================= fbcode/thrift/lib/cpp2/test/ProtocolBench.cpp relative time/iter iters/s serialized_size ============================================================================================= ObjectBinaryProtocol_write_LargeMapInt 24.88ms 40.19 NaN ObjectBinaryProtocol_read_LargeMapInt 263.72ms 3.79 8000010 ObjectBinaryProtocol_write_NestedMap 2.17ms 461.58 NaN ObjectBinaryProtocol_read_NestedMap 16.32ms 61.26 955550 ObjectBinaryProtocol_write_ComplexStruct 151.73ms 6.59 NaN ObjectBinaryProtocol_read_ComplexStruct 823.07ms 1.21 59006614 ObjectCompactProtocol_write_LargeMapInt 21.45ms 46.61 NaN ObjectCompactProtocol_read_LargeMapInt 241.03ms 4.15 7928804 ObjectCompactProtocol_write_NestedMap 2.25ms 443.92 NaN ObjectCompactProtocol_read_NestedMap 16.22ms 61.67 649304 ObjectCompactProtocol_write_ComplexStruct 153.06ms 6.53 NaN ObjectCompactProtocol_read_ComplexStruct 883.66ms 1.13 38637969 ============================================================================================= ``` Reviewed By: vitaut Differential Revision: D45419590 fbshipit-source-id: 43c55427c846f053520f71119c5050daa3572c68
