Fix: performance analytics spikes

[popuz]

What does this PR change?

Fix #2534

• disabled analytics for JsHeap (until we find the solution for it)
• change approach to Sort() and calculation of FrameTime samples, instead of one frame to do it in Update
• re-arranged hiccups calculation
• change string building for samples from float to int (as in old client)

Sort() optimization:

1. Basic idea of Sort() optimization comes from quite simple idea that Sorting already sorted array is much much more efficient than doing it on unsorted one.
2. Also, in this case we basically distribute sorting through the frames. Imagine bubble sort algorithm, it take one element and then bubble it up and do it for all N elements for the array. In our case, if it would be bubble sort, we would do it only for one element per frame. So at least N operations less. With the binary search it could be a bit different, but basic optimization idea still the same.
3. Further more, if needed now there are some heuristics and optimizations possible to apply, because of sorting ulong elements and also taking into consideration that new frame should be placed potentially near to the previous frame. I discarded that logic, because profiling showed that current version performs fast. I left more readable version. But we can do it in future if we feel the need.
4. Now CPU load of the sorting is actually scaling with the performance. Previously, we always were sorting 1000 elements, but now it depends. For higher FPS you sort more for lower FPS less. Distribution of it is like that
   11 ms (90 fps) - 1364 frames
   20 ms (50 fps) - 750 frames
   40 ms (25 fps) - 375 frames
