Subject: [PATCH 36/51] Avoid calling requestUpdate from wrong thread

In certain circumstances, we can get to createDecoration()
from the render thread (from QWaylandGLContext::makeCurrent)

Calling requestUpdate() from this secondary thread would
cause an assert, so we queue the call on the appropriate
thread instead.

This amends af7b60ade5c4be81cbc58eb18307c017d5594071.

Pick-to: 5.15 6.2 6.3 6.3.2 6.4
Fixes: QTBUG-105308
