Add not_user_triggered=true attributes to Signin_Impression User Actions

Breakscrumbs (feature which attaches steps to reproduce to crashlogs)
relies on not_user_triggered="true" to filter out non-interesting events.
This CL adds not_user_triggered="true" attribute to all
Signin_Impression as these action are logged during UI presentation, not
when user perfrom an action.
