ref(feedback): Remove deprecated user feedback APIs

Remove UserFeedback, captureUserFeedback and fromUserFeedback from the
core SDK, plus SentryUserFeedbackDialog and the SentryUserFeedbackButton
view and composable on Android. All were deprecated in 8.x in favor of
Sentry.feedback() and SentryUserFeedbackForm.

SentryItemType.UserFeedback stays because hybrid SDKs and envelopes
cached by older versions can still carry user_report items.

Resolves JAVA-493
