Add unassigned input gesture to send control alt delete in Remote Access

[SaschaCowley]

Is your feature request related to a problem? Please describe.

Users of Remote Access may find it tedious or inefficient to have to use NVDA's menus to send control+alt+delete to the controlled computer, especially if it is something they have to do often (e.g. if administrating a machine which requires the SAS to logon).

Describe the solution you'd like

Add an input gesture to send control+alt+delete, as well as the menu item. This would most likely be unassigned by default.

Describe alternatives you've considered

Add a default binding for the key. NVDA+alt+delete seems like a likely candidate, given its similarity to control+alt+delete.
Do not implement this gesture.

Additional context

This feature is already present in TeleNVDA

Note that in Remote Desktop, within the session. ctrl+alt+end translates to ctrl+alt+del. I wonder whether it makes sense to add this as an alternative approach. The problem with the script approach is that when you want to send ctrl+alt+del, you still have to switch control to the local machine before you can execute it.
