[jdk23] RFR: 8333854: IllegalAccessError with proxies after JDK-8332457

[Chen Liang]

Please review this patch, which is a backport of the fix in #19615 to JDK 23.

This is not a clean patch, because the old patch was done on JDK-8333479 (#19585) which was absent in JDK 23; however, the conflicts were small, and the only real changes were that `methodTypeDesc` and `classDesc` from `ConstantUtils` were not available, so the original approaches were retained. There is also import adjustments.

Testing: tier 1-3
