Fix EditText RenderNode invalidation bugs
EditText uses a TextDisplayList data structure to hold RenderNode
objects for optimized incremental drawing. This data structure uses an
isDirty flag to indicate when it has been invalidated and needs to be
re-rendered. This flag was not being computed correctly, leading to
excessive re-rendering.
This patch clears isDirty after rendering text into the RenderNode, so
that it can be reused until it is invalidated, and also explicitly sets
it when it is recycled.
