RustDesk Desktop Flutter Migration

• Solution
• TeamViewer style tab window, each window with a seperate flutter engine.
• Command line and Window mode in the same entry （Only one main function, as less wrapper as possible).
  • https://github.com/rustdesk/rustdesk/discussions/533#discussioncomment-2757147
• Texture layer rendering YUV directly (next version)
• Native UI style (next version, still use material design for the first version)
• Dark theme support
• Friendly taskbar
• Friendly tray
• More info (cpu/gpu/network/latency flow chart) on connection window
• May still use Sciter for win32 support
  • win32 not supported officially yet
• Whiteboard, Multi-user cursors (like AnyDesk)
• Bootstrap
