metrics: Add touch_jank.sql To share code between touch_jank.sql and scroll_jank.sql, this converts scroll_jank.sql into a templated metric stored in gesture_jank.sql. scroll_jank.sql and touch_jank.sql then just differ in their template parameters. Like scroll_jank.sql, touch_jank.sql only covers update/move events that reach the GPU. In future we will also track TouchMove events that don't, but will keep them separate so the events in each metric are actually comparable.
