Nick Hill 44cca1a26f Avoid allocations when wrapping byte[] and ByteBuffer arrays as ByteBuf (#8420)
Motivation:

Unpooled.wrap(byte[]...) and Unpooled.wrap(ByteBuffer...) currently
allocate/copy an intermediate ByteBuf ArrayList and array, which can be
avoided.

Modifications:

- Define new internal ByteWrapper interface and add a CompositeByteBuf
constructor which takes a ByteWrapper with an array of the type that it
wraps, and modify the appropriate Unpooled.wrap(...) methods to take
advantage of it
- Tidy up other constructors in CompositeByteBuf to remove duplication
and misleading len arg (which is really an end offset into provided
array)

Result:

Less allocation/copying when wrapping byte[] and ByteBuffer arrays,
tidier code.
