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.
