Switch rasterize_and_record_micro measurement to use RunPageInteractions.

After  https://codereview.chromium.org/966283002,
https://codereview.chromium.org/926213002,
https://codereview.chromium.org/927763002, all the pages used
with raterize_and_record_micro do not issue any interactions
in RunPageInteractions method, should this change should
not cause any functional changes to how the pages get run.
