[native] add safe area insets for android action sheet

Summary:
Another thing I encountered when testing the action sheet for the edit avatar flow on android is that if the nav buttons are visible then it partly covers the most bottom option on the action sheet. To fix this I used SafeAreaContext to set the paddingBottom of the action sheet which fixes the issue.

Depends on D7456
