QtSingleApplication: Introduce QTC_FREEZE_DETECTOR env var

Browse Source 
This may help with tracking the freezes in main thread.
By default, when QTC_FREEZE_DETECTOR is set, it detects
freezes above the 100 ms and prints the receiver object
and event type that triggered the freeze.

Change the default 100 ms threshold by setting the
QTC_FREEZE_DETECTOR to some different numeric value.
