Fix issue #5263361: Browser instance not created in application picker

The resolver activity was hiding the following activity from recents.

Also some other fixes: a little better memory use debugging, removed
some unneeded code from window manager, moved some system activities
into their own process, added some more running process information for
manage apps.
