fix: use pointer instead of std::function

Browse Source 
MSVC Compiler found an issue that there could be an attempt to
reference a deleted function when using std::function.
As the functionality of ioctlHelper::getGpuTime is very straightforward,
simple function pointer should be sufficient to make the job and
it mitigates overhead of std::function.
