W32 GUI: set active keyboard layout for gvim

[ant0sha]

New function "setkblayout" usable from tests is introduced, to control keyboard layout of running gvim. Usage example (expected to insert string "d€@ö" into current buffer, it requires my last PR #10814 - uses Alt+Ctrl as AltGr thus need to activate German keyboard layout as first):

call test_gui_event("setkblayout", #{kblayout: "DE", keycode: -99})

func SendMyKeys(keylist) let l:k = "" let l:t = "" for key in a:keylist "echomsg "k[i]=".key if l:k == "" let l:k = key "echomsg "l:k=".l:k else let l:t = key "echomsg "l:t=".l:k endif if l:t != "" if l:t == "du" "echomsg "k=".l:k.", t=".l:t call test_gui_event("sendevent", #{event: "keydown", keycode: l:k}) call test_gui_event("sendevent", #{event: "keyup", keycode: l:k}) endif if l:t == "d" call test_gui_event("sendevent", #{event: "keydown", keycode: l:k}) endif if l:t == "u" call test_gui_event("sendevent", #{event: "keyup", keycode: l:k}) endif let l:t="" let l:k="" endif endfor endfunc

" call SendMyKeys([73,"du"]) " <d ctrl, Lalt, e->€ q->@ ö ctrl_up, lalt_up> call SendMyKeys([68,"du", 17,"d",18,"d", 69,"du",81,"du",192,"du", 17,"u",18,"u"])

Hm, probably under CI there are no keyboard layouts available? That would explain why this test hangs under C I. No idea if layouts can be configured under CI somehow.
