Summary

When suspending compositing, SceneOpenGLShadow cannot cleanup cached
decoration shadow textures because the effects handler is already gone.

This sometimes can result in a crash when running kwin_x11 --replace
(we're hitting an assert statement).

To fix that, let's use the scene instead of the effects handler for
making the OpenGL context current.

Test Plan

No longer hit the assert statement:

ASSERT: "m_cache.isEmpty()" in file /home/vlad/Workspace/KDE/src/kde/workspace/kwin/plugins/scenes/opengl/scene_opengl.cpp, line 2025
Application::crashHandler() called with signal 6; recent crashes: 1
QCoreApplication::applicationFilePath: Please instantiate the QApplication object first
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kwin_x11 path = /home/vlad/Workspace/KDE/usr/bin pid = 5407
KCrash: Arguments: /home/vlad/Workspace/KDE/usr/bin/kwin_x11 --replace
