[Mirror Layers] Added functions to update mirrored layers info (2/4)

Added updateMirrorInfo and updateBufferInfoFromClone to ensure the state
and buffer of the clones are updated properly. updateMirrorInfo is
called when commitTransaction is called to update the drawing state,
children, and relatives. updateBufferInfoFromClone is called in
handlePageFlip after the real layer calls latchBuffer to ensure the
cloned layer gets the updated buffer and buffer info.

Test: No mirror request yet so everything runs normally
