Unpooled.wrappedBuffer will create ByteBuf on heap and the hasMemoryAddress will return false.
Unpooled.directBuffer will create ByteBuf on PooledUnsafeDirectByteBuf, and the hasMemoryAddress will return false.

@eolivelli Yes, we can ask for a new airlift release, but the code is already in branch-2.8, we need to find a way to get around first to unblock 2.8.1 release. |

…r upgrade to 0.20 (#11792) ### Motivation Due to aircompressor 0.19 can't work with heap buffer on JDK1.8, so #11594 use copy data to direct buffer to avoid NoSuchMethodError exception. Now aircompressor released 0.20 and #11790 has upgrade the aircompressor version to 0.20 to fix this issue, we can revert #11594 to avoid copy data to direct buffer to improve performance. ### Modification 1. revert Fix java.lang.NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer when enabling topic metadata compression #11594, but keep the tests.
