Dustin L. Howett (MSFT) 82f302b714 Shut down all controls under a tab before we remove it from the list (#4337)
This commit introduces a new recursive pane shutdown that will give all
controls under a tab a chance to clean up their state before beign
detached from the UI. It also reorders the call to LastTabClosed() so
that the application does not exit before the final connections are
terminated.

It also teaches TSFInputControl how to shut down to avoid a dramatic
platform bug.

Fixes #4159.
Fixes #4336.

## PR Checklist
* [x] CLA signed
* [x] I've discussed this with core contributors already.

## Validation Steps Performed
Validated through manual terminal teardown within and without the debugger, given a crazy number of panes and tabs.
