    Add 4-arg map override to FilterFileChannel (#15801)
    
    Java 22 added FileChannel.map(MapMode, long, long, Arena) which
    returns MemorySegment. The base FileChannel class provides a default
    implementation that throws UnsupportedOperationException. Without
    this override, any wrapped FileChannel based on FilterFileChannel
    would fail when the 4-arg map variant is called.
