QPixmapCache: guard against usage from non-main threads
Depending on the active QPA plugin, QPixmaps may now be created and
used also in non-main threads. But QPixmapCache is not designed to be
used from such threads, so add guards to ignore such access attempts,
both from application code and from Qt library code.
Such unsafe access would often cause a cryptical "~QObject: Timers
cannot be stopped from another thread" warning; that also disappears
with this fix.
