RFR: 8358686: CDS and AOT can cause buffer truncation warning even when logging is disabled

[Yudi Zheng]

When CDS and AOT loggings are disabled, HotSpot may still warn about `Mismatched values for property jdk.module.addexports:`. This warn message could be large and exceeds the current logging buffer length, and it leads to a non-informative message:

Java HotSpot(TM) 64-Bit Server VM warning: outputStream::do_vsnprintf output truncated -- buffer length is 2000 bytes but 4276 bytes are needed.

This PR skips reporting loading error when CDS and AOT loggings are disabled.
