Replace cacheLayout(...) with withCachedLayout(..., callback)

[david-tejada]

The function cacheLayout it's used for performance reasons, to avoid reflow. The issue right now is that every time I call cacheLayout I need to remember to call clearLayoutCache afterwards so that any function that calls any of the cached layout functions doesn't get stale data.

Similarly to what I did with withStack the function withCachedLayout would handle cashing the layout values and clearing them afterwards so that I don't need to remember to clear them every time.
