sm6250-common: Refined early phase offsets

Browse Source 
GPU takes long time(>8ms) when app was launching and closing.
This may because GPU is handling some heavy task like color conversion.
By setting NegativeOffset as 5ms to allow SF have more time to handle
when doing animation transaction and shift back 5ms with
early_app_phase_offset_ns such that app still has the same amount of
time to handle each frame.

Test: 1. Open Chrome from homescreen
      2. Swipe vertically to go back to home screen
      3. Measure the gpu completion time and "FrameMissed" count from systrace result
