RUM-18048: Fix Fabric text mapping in minified Android builds

[jonathanmos]

What does this PR do?

Fixes Session Replay text handling in minified Android builds using React Native’s new architecture.

R8 can rename an internal React Native text field, causing Session Replay to fail when reading styled text and generate repeated telemetry warnings. This change uses React Native’s supported accessor instead.

Pull request overview

Fixes Session Replay styled-text extraction for React Native new architecture on Android when apps are minified (R8), by removing reliance on reflective access to a private React Native field and switching to a supported accessor.

Changes:

• Replaces reflective lookup of React Native’s internal mSpanned field with ReactTextView.spanned for Fabric text color extraction.
• Simplifies FabricTextViewUtils by removing logger-based warning telemetry tied to the old reflection path.
• Updates unit tests to mock ReactTextView.spanned directly instead of stubbing the reflection helper.
