* Qt: Minor rewording on the storage controllers settings page
All translations updated accordingly
(the "Hard disk" string is still used in the PC5086 config and therefore
has been moved to a suitable place)
Also fix broken translations for ter/qua IDE controllers
* Qt: Don't attempt to translate storage bus names
* Qt: Remove translations for non-generic joystick names
These weren't actually supposed to be translated
Thrustmaster Formulas were left in because of "with/out adapter"
* Qt: Tooltip and icon text fixing
* Restore unused strings that were to be used as tooltips
for Ctrl+Alt+Del/Esc buttons
* Consistently define tooltips and iconText to avoid mnemonics showing
in CJK languages
* Remove tooltips from actions that only show up in menus
* Qt: Add ACPI shutdown to menu
* Qt: Drop "SoundFont" string from translations
This is a brand name that shouldn't be translated
* Qt: Replace three-dot ellipsis with a single-character one
* Manager: workaround for font mismatch on language change
Add a native event filter for dark mode update, move the function
that queries the current theme to qt_util.cpp and make widgets
with custom stylesheets update their style on update
