Update dwell ripple parameters

Targeted effect:
* Immediate visual response on touch down at
  sufficiently visible radius for variable finger sizes.
* Then decelerate radius expansion to convey tension / elicit
  force and constrain at limited max radius past first stage.
* Bump values on non-AOD surface to improve visibility with
  more variable backgrounds.

Test: `adb shell cmd statusbar auth-ripple dwell` expands ripple (but
doesn't animate the retract)
Test: manual, atest SystemUITests
Bug: 198864174
