Implement selectable property for Text for fabric

[jonthysell]

Implement the selectable property for the fabric implementation of Text.

This property was available in RNW Paper via TextViewManager.

See https://reactnative.dev/docs/text#selectable for details.

This can be fixed when upstream react-native fixes their macro conversion of selectable prop from JS to native. Added PR for the same : Text: Fix selectable prop mapping (was isSelectable) for Fabric - ensure correct macro conversion by iamAbhi-916 · Pull Request #51187 · facebook/react-native

After teh above is merged and integrated to RNW , then we need to add pointer/touch handlers in ParagraphComponentView that, when selectable is true, allow the user to select text

This would be incredibly helpful to have!

What does the roadmap for this look like now that https://github.com/facebook/react-native/pull/51187 was closed without merging?

[iamAbhi-916]

@austinhallock we created a new pull which was backward compatible and that got merged. ref : https://github.com/facebook/react-native/pull/52599.

Will be adding this support for react native windows in sometime !
