> Blink new binary format is based on MemorySegment.
> Improve MemorySegment to provide copyToUnsafe copyFromUnsafe and equalTo.
> 1.copyUnsafe: If we want to copy int[] data into MemorySegment, we can only use int to
set Int one by one, which is inefficient. We can copyFromUnsafe directly.
> 2.equalTo: Provide an efficient equalTo.
