Settings: Add heads up blacklist options. (2/2)

Remove SystemSettingSwitchPreference.

We should not introduce one-off UI patterns when there are plenty of
examples where the same usage pattern (a feature on its own
PreferenceScreen with a global enable switch in the action bar) is
handled differently everywhere else (e.g. daydream, cast display,
blacklist). This makes for inconsistent UX.
Also, there are discoverability issues: As there's no other case of a
preference with an embedded control widget opening another preference
screen, users won't expect to find another screen behind it.
Additionally - but entirely subjective - the control looks plain ugly,
as the preference padding is too large for the large switch.

Hide heads up settings and show a notice if heads up is disabled.

This follows a UI pattern used at several other places, such as
daydream, screencast, profiles or blacklist settings.

Settings: Add heads up quicksettings tile. (2/2)

Settings: Fix switch state being out of sync.

    - Since QS Tile can also set state of Heads up now,
    we have to set a content observer for the action bar
    switch.

more code: Deduplicate adapter-of-installed-packages code.

Change-Id: Id655da05fb0f434ff93dec27591208c9daf2dfc6
more code: Add some system packages to package list adapter.

As we're using the adapter for notification control stuff, we need to
include those packages, too, as they're throwing notifications as well.

Also optimize code a little.
