[KBSWITCH] Refactor on layout numbers (#8052)
We believe the power of simplicity. JIRA issue: CORE-20142 - Rename g_nCurrentLayoutNum as g_iKL for simplicity. - Make g_iKL zero-based indexing. - Add ID_LANG_BASE id for language menu items and adjust ID_EXIT/ID_PREFERENCES values. - Fix KbSwitch_OnNotifyIconMsg function.
