David Vacca 8f6aee0df5 Create experiment to increase size of TextMeasureCache and enable in RNPanel apps ...

Summary:
Fabric uses a cache where it stores the result of the text measurement in C++ (to avoid unnecessary text measurement that are very costly). This cache has a "max size" of 256 and this size is not enough to store all the texts we have in the screen

In my tests, the amount of texts being measured are ~290 and after scrolling many times they increase to 611.

This diff increases the size of the TextMeasure to 1024 for users in the experiment. As a result this improves performance of HoverEvents by +5x times (see test plan)
