Move insights up and down in the list

[planarvoid]

Fixes #8953
This is related to the FluxC PR - wordpress-mobile/WordPress-FluxC-Android#1088

This PR adds an overflow menu to each Title on the Insights tab. This menu contains button to move the item up, down or remove it from the list.

To test:

• Open Stats
• You see only Latest post summary, Today stats and Most popular block in Stats
• You see an button in each title
• Clicking the button opens a Popup menu
• The popup menu contains 3 items - Move up, Move down and Remove
  • The first item doesn't contain the Move up action
  • The last item doesn't contain the Move down action
• Clicking the actions moves the block up/down/removes it from the list
• Adding blocks is not yet implemented so be careful with testing it

This is pretty cool :). I've found a couple of quirks:

• When you tap on the overflow menu of a card and dismiss it, it's not possible to tap it again. You have to first tap a different card's menu button and then it works again.
• When you move the Latest Post Summary down and use PTR, the screen is automatically scrolled down to that card for some reason.

@0nko thanks for the check 👍 , I think I've fixed both the issues (at least I cannot reproduce them anymore)

Confirmed, the issues are fixed and the menu works great! Thanks! 💯
