cc: Only report calc_draw_props_time.

The perf dashboard is configured to monitor every trace output by the
cc_perftests. Here, we were outputting two traces that represent the exact
same thing. This only causes more work for the perf sheriffs. So I'm cutting it
down to one.

Incidentally, this eliminates a bug where the dashboard thought that a higher
count was a regression.

This also improves the precision by supporting decimals.
