Use allocator when constructing ByteBufHolder sub-types or use Unpool… (#9377)

Motivation:

In many places Netty uses Unpooled.buffer(0) while should use EMPTY_BUFFER. We can't change this due to back compatibility in the constructors but can use Unpooled.EMPTY_BUFFER in some cases to ensure we not allocate at all. In others we can directly use the allocator either from the Channel / ChannelHandlerContext or the request / response.

Modification:

- Use Unpooled.EMPTY_BUFFER where possible
- Use allocator where possible

Result:

Fixes #9345 for websockets and http package
