[jdk16u] RFR: 8253910: UseCompressedClassPointers depends on UseCompressedOops in vmError.cpp

[Aleksey Shipilev]

This improves hs_errs after JDK 16 change, which might be confusing (compress klass ptrs are enabled, when hs_err is pointing out in only one place in heap info). 

Additional testing:
 - [x] Linux x86_64 fastdebug `tier1`
