installer: Allow Alt+Shift toggle from non-Latin keyboard layouts.
Fixes <https://bugs.gnu.org/40493>. * gnu/installer/newt/keymap.scm (%non-latin-layouts): New variable. (%non-latin-variants): New variable. (%latin-layout+variants): New variable. (toggleable-latin-layout): New procedure to compute combined layouts. (run-keymap-page): Use it. (keyboard-layout->configuration): Apply it in config.scm. (run-layout-page): Mention Alt+Shift. * gnu/installer/keymap.scm (kmscon-update-keymap): Pass on XKB options. * gnu/installer/record.scm (<installer>): Adjust code comments. * gnu/installer.scm (apply-keymap): Pass on XKB options. (installer-steps): Adjust code comments. * gnu/packages/patches/kmscon-runtime-keymap-switch.patch: Apply XKB options.
