This macro, similar to QTC_SCOPED_TIMER(), measures the time spent in a block of code. In addition, the time spent in a block is saved in a static variable. This macro enables measuring a cumulative time spent inside a certain block of code for all invocations. When a long freeze is being tracked, and QTC_SCOPED_TIMER() indicates that the most of the freeze is spent inside a loop with a big amount of iterations, placing QTC_STATIC_SCOPED_TIMER() inside the loop may detect the part of the loop that composes in total for the longest freeze. In contrary to the QTC_SCOPED_TIMER(), this macro it doesn't print the message when it's entered. It prints the output at first hit, and later, as not to clog the debug output, only at 10ms resolution.
