With D23951 we greatly improve the discoverability of the panel edit mode, so there isn't a need for a button in the panel anymore that just takes up space (especially since with D23951 we're basically always in unlocked mode) and we get asked about how to remove it from time to time. This also cleans up the panel editing options:
- Only show "Show Alternatives..." in panel edit mode
- Remove "Lock Widgets" option from the panel edit mode, like in D23951
