Change the all apps atomic transition duration to 150 ms

Test: manual

TL;DR;; this value is used for tap on qsb all apps container
atomic transition. 320 is value that used to be used in R
when all apps travel distance used to be entire window height.
In S, we reduced the travel distance to 1/3 of the height.
