RFR (S): Avoid touching typeArrayKlass klasses

[Aleksey Shipilev]

Hi,

In the previous change [1], we started touching typeArrayKlasses eagerly during
the Universe scan. But now Roman discovered that typeArrayKlass::oop_oop_*
actually ignores them completely, because they never move. So our Universe
change is at least redundant, and may even set us for failure now exposing
typeArrayKlasses for movement.

Fix:

Testing: hotspot_gc_shenandoah

Thanks,
-Aleksey
