Add 'view profile' to message long tap

Problem

This is being done largely as a counter spam mechanism, so that users can easily load up a person's profile and subsequently block them if they are flooding a chat.

Also, you can not currently long tap a sticker, because the reply and copy UI is not built yet. The view profile option is valid for stickers now though.

Note: labeled v1 release, but not a v1 hard blocker.

Implementation

Use the same menu option that we do in overflow menus:

Acceptance Criteria

1. New option to view profile is available when you long tap on a message
2. When you long tap on a sticker, you get the view profile option only
