Remove PhabricatorProfileHeaderView in favor of PhabricatorHeaderView
Summary:
We have this old view which is only used in two places and looks the same but has totally different markup. Get rid of it.
@chad, I'm generally going to move the user/project profiles a step toward looking like other object detail view with the custom field stuff. Not sure if you have any grand vision here; we can easily do something else later since this is like 80% "delete weird epriestley one-offs that don't look quite right in favor of standard elements".
Test Plan: {F49324} {F49325} {F49326}
