ImGui histogram container improvements (#4630)

Browse Source 
* Added auto scale mode that uses a running average to expand and shrink the visible vertical range.
* Added option to set the move direction and either push new values to the front of the buffer (left) and make the histogram move to the right or the inverse.
* Changed the camera monitor to use auto scaling as well as the current one was not showing anything because of an outlier.
* Pre-fill the histogram with zeros so that the first pushed sample moves in without horizontal scaling effects which made it hard to read out any information from the histogram.
