Earlier, keyboard shortcuts were not supported for non-latin keyboard layouts. This commit adds support for it. Keyboard can be: * configured to type latin text, with the QWERTY, AZERTY, etc layout. * configured to type non-latin text. For non-latin users, if a shortcut requires a key and it is not present on the keyboard, they press the same physical key that a QWERTY user would press. Pressing QWERTY equivalent key is not a Zulip specific requirement, non-latin users have confirmed in CZO that they use the same behaviour on other applications. Algorithm: We need to determine the key combination pressed in a consistent way, irrespective of the keyboard layout. For keyboard layouts (e.g. QWERTY) where `event.key` results in printable ASCII characters or named key attribute values like "Tab", "Enter", etc., we use `event.key` directly to determine the key combination. For layouts where the character defined for a hotkey can't be typed directly (e.g. 'a' in Cyrillic), users press the same physical key combination that a QWERTY user would use (e.g. 'ф' on Cyrillic maps to 'a' on QWERTY). In such cases, we derive the key combination (QWERTY equivalent) using `event.code` and the `CODE_TO_QWERTY_CHAR` map. Here `event` is "keydown" event. Once, the key combination is determined the action to perform is executed. Fixes: #19605.
