windows: Fix keystroke & keymap (#36572)

Closes #36300

This PR follows Windows conventions by introducing
`KeybindingKeystroke`, so shortcuts now show up as `ctrl-shift-4`
instead of `ctrl-$`.

It also fixes issues with keyboard layouts: when `use_key_equivalents`
is set to true, keys are remapped based on their virtual key codes. For
example, `ctrl-\` on a standard English layout will be mapped to
`ctrl-ё` on a Russian layout.
