Add `enableBreadcrumbTextExtraction` option on `SentryAndroidOptions`

[antonis]

Add a boolean enableBreadcrumbTextExtraction (default true) on SentryAndroidOptions. When false, skip all text-based label extraction for interaction breadcrumbs — only resource ID, class name, and sentryTag are captured.

Provides a global opt-out for apps with PII concerns about text content appearing in breadcrumbs.
