[Accessibility] Add a reading mode function for screen reader #971
Description
Introduction
It woud be useful to integrate a reading mode function to instruct the screen reader to spell a word char by char with punctuation.
Details
iOS exposes a speechSpellsOutCharacters to do this. I don't know if there's a corresponding function in TalkBack, but it would be useful to have a funcrio like this in RN. At the moment there is no practical way to do this apart from a custom mapping function (e.g. ","->"comma"; "A"->"Capital a"), which is quite an unaffordable nightmare especially when considering multilanguage.
Discussion points
Maybe adding a function in accessibility API could be a viable way to do this, instead of adding a dedicated prop as the range of contexts when this is needed would be quite limited.
Or maybe both?
