Cleanup: remove VNDK APEX exception from binder

VNDK APEX is now built with vendor variants instead of apex variants.
Now, no need to whitelist vndk apex in libbinder's apex_available or use
__ANDROID_APEX_COM_ANDROID_VNDK_CURRENT__  for stability check.

Bug: 146758869
Test: m / flash / device boots
