[SR] Recursive unmasking

### Problem Statement

Currently, [unmasking a component](https://docs.sentry.io/platforms/react-native/session-replay/privacy/#general-masking-rules) affects only the component directly wrapped with ``. For some use cases where the actual text components are two or more levels down in a nested component tree, this can become cumbersome and may also require unwanted updates to component code (e.g. several levels into a Button component - user wants to unmask the button label).

### Solution Brainstorm

Provide an API to mark a component for unmasking recursively.

Note: There was a conscious decision not do to this initially, because it makes it easy to unmask more than intended. If this is implemented, it should be very clear to the user what happens, and very hard/impossible to do it unintentionally.

E.g. something like `` (default: false)

Inizia esaminando l’API Sentry.Unmask esistente e le regole di mascheramento React Native collegate. Definisci esplicitamente un opt-in ricorsivo e il comportamento dei suoi discendenti, quindi verifica che il testo annidato venga smascherato solo quando richiesto e che lo smascheramento ordinario rimanga invariato.
