Remove Device VNDK version usage from Soong

As of VNDK deprecation, Device VNDK version should no longer be used
from build. This change removes all references on Device VNDK version
and related logic with it.

Bug: 330100430
Test: AOSP CF build succeeded
Change-Id: Ibc290f0b41e8321f80c75c69f810223989af68dc
