[jdk21u-dev] RFR: 8315130: java.lang.IllegalAccessError when processing classlist to create CDS archive [v2]

[Timofei Pushkin]

> Fixes a error which significantly complicates the use of static CDS in some applications with user-provided class loaders (workarounds require either manually editing the generated CDS classlist which is error-prone, or switching to dynamic CDS which has its own implications, or rewriting the application which is not always possible).
> 
> The conflicts were trivial: a few neighboring methods missing from this version and not directly related to the change.
> 
> The PR depends on #1833 and #1834 though it can be rewritten not to if needed.
> 
> Testing besides the CI (performed on macos/arm64): `runtime/cds`, a minimal reproducer app described in the original bug report.
