fix(linux): migrate to qt tray

[ReenigneArcher]

Description

Migrates system tray library on Linux to use Qt version, from LizardByte/tray#104

TODO:

• clicking pair notification does not open Sunshine config ui
• left clicking tray icon does not bring up menu (double click works)
• menu opens near top left of screen on Wayland, okay on Xorg
• cannot dismiss menu by clicking outside of it on Xorg, okay on Wayland (esc key allows dismissing in Xorg)
• KDE Plasma's settings for tray icon visibility don't allow changing the tray icon visibility
• Using Qt6, icon is not setup properly (uses generic ... replacement)
