Fix install-from-dmg.

When installing from a disk image, the browser relaunched from the
newly-installed location should follow the proper first-run experience if
appropriate.

When installing from a disk image, existing dock tiles should be reused, and
dock tiles pointing at the application on the disk image should be replaced
with ones pointing at the newly-installed location.

When installing from a disk image and requesting administrator access (because
the user does not have permission to install to /Applications), Keystone
should be promoted to a system-level install, and Chrome's Keystone ticket
should be promoted to a system Keystone ticket.

The custom panel key window tracking stuff doesn't need to maintain strong
references to key windows, but does need to be beefed up for thread safety.

Chrome doesn't need to wait until it's mostly started up to run the
install-from-dmg flow. It should do it early, avoiding delays and reducing the
possibility that harmful services will start running.

BUG=119325
TEST=obvious from the above and the bug
