Disable screenshot actions for work profile.

Additional work will be needed to ensure intent launching works properly
for these, defering that to post-launch.

Behavior changes all protected by the flag SCREENSHOT_WORK_PROFILE_POLICY
but had to move the smartActionsEnabled computation to be passed around instead
of an instance variable (so it could honor the new constraint).
