Bug 918651 - part 7b - fix Layers{Surfaces,Messages}.ipdlh header bootlegging; rs=ehsan

LayersSurfaces.ipdlh declares itself as |using| a bunch of types that only
get used in LayersMessages.ipdlh.  Since intelligent include-placing
recognizes that these types are not used in LayersSurfaces.h, the necessary
header lines get left out of the generated LayersSurfaces.h, leading to
compilation problems on some platforms.  Fix this by moving the appropriate
lines to LayersMessages.ipdlh.
