Screenshot: Add select area option

Add 'Select area' button to Screenshot that when clicked, allows the
use of crosshairs to select a region to screenshot; functionally similar
to and inspired by Snipping Tool/Win+Shift+S on Windows and Cmd+Ctrl+4
on Mac when selecting using the primary mouse button. When using the
secondary mouse button or clicking while shift is held, the selected
area can be resized and moved, and confirmed by pressing enter or double
clicking.

Also, add a shortcut such that if the super key is held when prtscrn is
pressed, Screenshot will be launched in area select mode.

Also, add radio buttons to select between whole screen, active window,
and selected area, and disable active window, window border, and
selected area options if inapplicable.

See #18568 and #13456
