APEXes contain VNDK libraries when VNDK is deprecated

Currently vendor APEX can link to VNDK when 'use_vndk_as_stable'
property is set as true. However, when VNDK is deprecated, all former
VNDK libraries should be included in the vendor APEX despite of property
value. This change ignores use_vndk_as_stable when VNDK is set as
deprecated.

Bug: 290318998
Test: aosp_cf_x86_64_phone with WITH_VNDK=false build checked that
Vendor APEX contains all required VNDK libraries within the APEX
