Mobile App Session Replay: Ability to disable or mask touch capture per screen

### Problem Statement

Currently, mobile Session Replay captures raw tap and drag gesture coordinates globally via the native touch tracker. While this is incredibly useful for debugging user flows, it introduces security/privacy risk on sensitive screens. Even when the mask strategy is strict and the keyboard doesn't show, the global touch overlay still records and displays the exact coordinates of user taps/drags over the relay. If a user is typing on a standard QWERTY keyboard or a fixed-layout numeric keypad, an observer can easily deduce inputs (passwords, PINs, or PII etc) just by looking at the tap indicator positions on the masked replay.

I would like to see the ability to drop touches for components/views.

### Solution Brainstorm

- Extend `Sentry.Mask` with a prop to disable touches? Or maybe a new wrapper `Sentry.MaskTouches`?
- Failing that, we'd be better off with a global way to pause/unpause or just don't record any at all

### Are you willing to submit a PR?

None

Start by tracing the native touch tracker and the existing Sentry.Mask API. Compare the proposed per-component masking, a Sentry.MaskTouches wrapper, and global pause options. Done means sensitive screens or components no longer expose tap and drag coordinates in Session Replay, with behavior verified on the affected mobile platforms.
