feat(ui): Enhance Virtual Keyboard for US (jetkvm#449)

* feat(ui): Add Ctrl+Alt-Backspace combination key to Virtual Keyboard

Fixes jetkvm#445 (somewhat)

* fix(ui): Correct virtual keyboard display when shift key is down.

Somewhere along the way, the handling of the shift-key state for letters and numbers was lost and we stopped displaying the capital/symbol for the key.
Also update page up and page down to have the space in the on-screen key.

* feat(ui): Add missing keys for virtual keyboard

Enable insert, delete, numpad equal, print scree, scroll lock, pause, system request, break keys.
