Revert "Remove a compat hack SurfaceView#setWindowType()"

This CL reverts my previous CL [1] that aimed to get rid of
a nasty compatibility hack that was introduced for Bug 36345857.

For those who are interested in, what happenned are:

 1. @hide method SurfaceView#setWindowType() was removed [2].
 2. It broke some app (Bug 36345857).  We had to work around
    it by re-introducing SurfaceView#setWindowType()
    temporarily [3].
 3. Some app switched to the correct implementation when
    running on Android O devices.
 4. We removed that compatibility hack [1] (Bug 62054282).
 5. Android O MR1 is set to be "REL" [4].
 6. It broke some app, probably because of some unfortunate
    mistake in the version check logic in that app.
 7. We end up introducing the same hack again for O MR1.
