Fix popup menus and window state, add window actions (#10155)

[toreonify]

Full description can be found in #10155.

Description

Theese fixes apply to X11 client in FreeRDP.

• Context menus in some applications disappear almost instantly, cannot use them. Some application draw menus with different window flags from system context/popup menus. I've tested some combinations of flags that theese menus use. Other windows work as usual, except for dialog windows that show up as a separate window in taskbar on client side. Handling of window state flags in Windows is somewhat confusing.

• Window state is not syncronized correctly with Windows side When window was maximized, then restored, then switched to another window in RDP or other X11 window, it maximized back. Maximized window state was not set on X11 window when Windows sent this event to client.

• Added allowed actions for windows Client side created a X11 window without _NET_WM_ALLOWED_ACTIONS and allowed sending signals to maximize windows that aren't supposed to be. They can be maximized in theory, but there aren't any buttons in titlebar or in window context menu.
