Add state to check if Resize Observer Loop Limit error was dispatched

Currently, if the resize observer loop limit error is dispatched and
the error callback affects layout causing lifecycle state to be \<
kPrePaintClean, an infinite loop may occur causing unexpected behaviour.

To fix this, state is added to the resize observer controller in order
to achieve the following flow:

• Loop limit error is reached
• Error callback causes lifecycle state to be \< kPrePaintClean
• Lifecycle steps including resize observer steps are run again to move
  state to kPrePaintClean
• Error is not dispatched a second time
• Proceed to the paint step
