Rationale (410857):
We should move the "DrainOverflowLines" block before "ResolveBidi" block
if we can - this way we would have a simpler frame tree to deal with
during bidi resolution and possibly create fewer frames in some cases.
Includes two changes:
* aContainerSize of ReorderFrames, RepositionInlineFrames, RepositionFrame are changed to aContainerISize;
* the type of aContainuationStates in the functions above is changed to const pointer.
