Move "prePaint" under the "Update Layer Tree" devtools timeline step

Move "prePaint" under the "Update Layer Tree" devtools timeline step

Slimming paint invalidation (--enable-slimming-paint-invalidation) moves
paint invalidation to a new "pre-paint" document lifecycle stage. This
patch moves prePaint under the "Update Layer Tree" timeline category, and
adds a comment to move this under "Paint" for slimming paint v2 (see
discussion in https://codereview.chromium.org/2623613008).

This keeps failing but I do not see how
RequestCoordinatorFactoryTest.BuildRequestCoordinator is related to this patch.
Trying again...
