Problem: Cannot map Super Keys in GTK UI
(Casey Tucker)
Solution: Enable Super Key mappings in GTK using <D-Key>
(Casey Tucker)
As a developer who works in both Mac and Linux using the same keyboard,
it can be frustrating having to remember different key combinations or
having to rely on system utilities to remap keys.
This change allows `<D-z>` `<D-x>` `<D-c>` `<D-v>` etc. to be recognized
by the `map` commands, along with the `<D-S-...>` shifted variants.
```vimrc
if has('gui_gtk')
nnoremap <D-z> u
nnoremap <D-S-Z> <C-r>
vnoremap <D-x> "+d
vnoremap <D-c> "+y
cnoremap <D-v> <C-R>+
inoremap <D-v> <C-o>"+gP
nnoremap <D-v> "+P
vnoremap <D-v> "-d"+P
nnoremap <D-s> :w<CR>
inoremap <D-s> <C-o>:w<CR>
nnoremap <D-w> :q<CR>
nnoremap <D-q> :qa<CR>
nnoremap <D-t> :tabe<CR>
nnoremap <D-S-T> :vs#<CR><C-w>T
nnoremap <D-a> ggVG
vnoremap <D-a> <ESC>ggVG
inoremap <D-a> <ESC>ggVG
nnoremap <D-f> /
nnoremap <D-g> n
nnoremap <D-S-G> N
vnoremap <D-x> "+x
endif
```

Problem: Keymap completion is not available
Solution: Add keymap completion (Doug Kearns)
Add keymap completion to the 'keymap' option, user commands and builtin
completion functions.

Problem: The keyboard state response may end up in a shell command.
Solution: Only request the keyboard protocol state when the typeahead is
empty, no more commands are following and not exiting. Add the
t_RK termcap entry for this.
Problem: Still using simplified mappings when using the kitty keyboard
protocol.
Solution: Use the kitty_protocol_state value to decide whether to use
simplified mappings. Improve how seenModifyOtherKeys is set and
reset.
Problem: Cannot debug the Kitty keyboard protocol with TermDebug.
Solution: Add Kitty keyboard protocol support to the libvterm fork.
Recognize the escape sequences that the protocol generates. Add
the 'keyprotocol' option to allow the user to specify for which
terminal what protocol is to be used, instead of hard-coding this.
Add recognizing the kitty keyboard protocol status.
Problem: A silent mapping may cause dots on the command line.
Solution: Don't show dots for completion if they are not going to be removed
again. (closes#11501)
Problem: "$*" is expanded to "nonomatch".
Solution: Only add "set nonomatch" when using a csh-like shell. (Christian
Brabandt, closes#9159, closes#9153)
