sddm-theme: focus password field after changing session or kbd layout
requested to merge ngraham/plasma-workspace:focus-password-field-after-changing-session-or-keyboard-layout-in-sddm-login-screen into master
We already force focus to the password field after showing or hiding the virtual keyboard, since otherwise it's annoying and you have to manually re-focus it. Let's do the same for the session and keyboard layout choosers to save the user a click and some annoyance.
