Offer fragment's lifecycle-aware breadcrumbs logger

[wzieba]

Similar to this: https://github.com/getsentry/sentry-java/blob/main/sentry-android-core/src/main/java/io/sentry/android/core/ActivityLifecycleIntegration.java but for fragment.

This will have to be manually added by clients into fragments lifecycle as suggested in https://github.com/woocommerce/woocommerce-android/pull/3891#pullrequestreview-645795013
