[request] Remove client decorations (linux/wayland)

[FabianLars]

This is mostly about #979 / #977 tauri-apps/tauri#10702

From what i've heard so far the change caused more harm then good because now tao/tauri windows behave very non-wayland like.

First of all, the Titlebar buttons shouldn't have been a reason for this PR. If wayland doesn't show min/max buttons by default that's not our problem and if users want those buttons they should use the system settings to get them back.

Then the the more important problem, the 71 error code / resizing in general.

On wayland it's a very well known issue that app windows don't restore their state, but this is not our problem to fix if wayland doesn't want us to be able to do this.
I can't remember about Gnome, but KDE for example is working on this https://bugs.kde.org/show_bug.cgi?id=436318 etc

imho the better solution would have been to a) document wayland specific behavior as much as we can and b) :

• Make set_size methods fail non-panicking if they had issues (didn't find mentions of this)
• webkitgtk internal errors mentioned in #10702 either shouldn't be our concern, or we should finally add the mentioned workarounds (env vars) that also fix other issues.
• moving and resizing with the native decorations not working should really have some other fix. i can't believe that this requires client decorations because this used to work fine without them for such a long time before.
