feat(anr): Profile main thread when ANR and report ANR profiles to Sentry

[markushi]

:scroll: Description

Adds ANR (Application Not Responding) profiling integration that profiles the main thread when an ANR is detected and reports the captured profiles to Sentry.

Key Changes:

• New AnrProfilingIntegration to capture profiles during ANR events
• AnrProfileManager to manage ANR profile lifecycle
• AnrCulpritIdentifier to identify the culprit code causing ANR
• Stack trace and profile aggregation utilities
• Added comprehensive tests for ANR profiling functionality

:bulb: Motivation and Context

This feature enables better ANR diagnostics by capturing profiling data at the time of ANR detection, allowing developers to identify performance bottlenecks and problematic code paths causing application hangs.

:green_heart: How did you test it?

• Unit tests for AnrCulpritIdentifier with various stack trace scenarios
• Integration tests for AnrProfilingIntegration
• Profile manager lifecycle tests
• Stack trace converter tests

:pencil: Checklist
