  [GTK] Remove the code to keep previous layer tree host alive
https://bugs.webkit.org/show_bug.cgi?id=261672

Reviewed by Alejandro G. Castro.

This was used for the ondemand mode when we allowed to exit accelerated compositing mode,
but now we force always compositing the first time we enter accelerated compositing mode.
The only way to exit accelerated compositing is by setting the policy to never, in which
case we don't want to keep the previous layer tree host since it's unlikely we enter it
again soon.
