[Development] QtMultimedia && QML - hard performance regressions on Windows

[Denis Shienkov]

I have checked it again on other PC and see following:

1) If I compile the QtMultiMedia from the 5.6 branch (self-compiled with
the Qt 5.6.0) and there are the same issue!!!

2) But if I use QtMultiMedia from the 5.5 branch (self-compiled with the Qt
5.6.0), then this issue does not exists!!!

PS: I have added this info to the bug-tracker too
