Improved measurement of rasterize time and pixels rasterized.

 - Reporting minimum rasterize time out of multiple runs excludes
   time when the raster thread is de-scheduled and it excludes cache effects.
   In order for this to work reliably, slow-down-raster-scale-factor needs to
   be set to a large value (e.g. 100).
 - Fixed computation of number of pixels rasterized to use the intersection
   of content_clip and canvas_rect, instead of content_clip.
 - The improved measurements are designed for a new rasterize and paint
   benchmark that will be committed in a spearate CL.
- Separated paint time (direct rasterization without prior recording to an SkPicture) from record time
