[TouchLatency] Update style of touch latency

Again have to change the style to exclude the app from edge 2 edge
I think our testing app is low priority and can be opt out
from the edge to edge for now.
Without this change the fps: number that we have in the display
will be behind the toolbar and won't be visible.

Test: manual
