Map aria-* props to equivalent accessibility props

[intergalacticspacehighway]

React native web's 0.15 version mentions that the undocumented support for aria-* props will be deprecated in the future.

In the current approach for React native aria, we use React Aria's hooks for the web which returns aria-* props.
We'll have to create an aria-* to accessibility* mapping to support the future versions of rn-web.
e.g. aria-pressed returned from React Aria will be mapped to accessibilityPressed.

Todo - Create a mapping function that maps aria-* attributes returned from react aria to accessibility* props.
