[RUM-11723] [V3] Expose view attributes API

[sbarrio]

What does this PR do?

This PR exposes the native RUM view attribute API that allows users to add and remove attributes that will be linked with the view currently active.

Motivation

We need to expose the new APIs added for V3 to be usable from React Native.

Additional Notes

The native Android SDK does not expose single attribute function to add/remove but the iOS one does. To keep the API clean and consistent at React Native level we have exposed the same 4 functions present on iOS, but when calling addAttribute/removeAttribute on Android the native layer will internally wrap the passed parameters and call addAttributes/removeAttributes with them, achieving the same results across the board.

Example of view attributes:
