There is currently no way to disable to context menu that automatically appears over a TextInput. This is especially troublesome if you would like to disable the user from pasting text into certain fields. This PR adds a `contextMenuHidden` property to TextInput that will hide it.

I'm not sure if testing is necessary here. I would be happy to investigate further on how this would be tested, if deemed necessary!
