Check for buffer backed by shared segment kicks in in unexpected places

The following test fails:


@Test
public void readOnlyByteBufferFromSharedNativeSegment() {
   try (MemorySegment segment = MemorySegment.allocateNative(8).share()) {
     var byteBuffer = segment.asByteBuffer();
     // This fails for native segments, but passes for heap segments.
     // Throws UOE: ByteBuffer derived from shared segments not supported
     byteBuffer.asReadOnlyBuffer();
   }
}

The problem is that some of the slice constructor are using the internal DirectBuffer::address method, which is where the check for shared buffer takes place.
