Add support for class lookup by name in CP for JITServer/AOT

[cjjdespres]

Classes can now be looked up by signature in a constant pool when compiling AOT or remote methods. An SVM assertion failure relating to shadow symbols has also been fixed using this new support.

Fixes: #20669

I think it's #17975.

The aarch64_linux list failed in cmdLineTester_criu_jitserverPostRestore_1 because of the known can't bind server address: Address already in use.

The ppc64_aix list failed in jdk_security2_0 in javax/crypto/Cipher/ByteBuffers.java because of a timeout:

There have been some "Agent communication error" failures in this test recently (#19962), but I'm not sure if they're related. There is a Cannot contact p8-java1-ibm07: java.lang.InterruptedException message in the same failure, which does appear in the linked issue at least.

I started a 10x grinder for the AIX failure here: https://openj9-jenkins.osuosl.org/job/Grinder/4006/

[cjjdespres]

Three failures in the AIX grinder were

TEST RESULT: Error. Agent communication error: java.io.EOFException; check console log for any additional details

matching #19962, and the other seven were successful.

[mpirvu]

I had another 10 iteration grinder with the nightly build: https://openj9-jenkins.osuosl.org/job/Grinder/4007/
There is also a failure with
15:18:17 TEST RESULT: Error. Agent communication error: java.io.EOFException; check console log for any additional details
so this PR is not the culprit. All in all, this PR is ready to be merged.
