jankometer: Remove.

jankometer: Remove.

The histograms don't seem to be used anymore (do not show up in UMA). The
hang-detector and about:profiler produce relevant useful data for detecting jank.

BUG=none

FWIW: I think we get more results these days from the hang-detector, and we also
have the about:profiler to show a lot of data. 

Getting rid of the jankometer SGTM.

+cc Brett in case he had a different perspective (he originated the Jankometer I
think, even if I toyed with it)
+cc Raman in case he has a use case (he wrote the watch-dog time a.k.a.,
hang-detector)

Mind giving the approval from @chromium.org so the tools are happy? :)
