RFR: 8294058: Early use of lambda introduced in JDK-8285263 cause startup regressions in 20-b02

Tue Sep 20 11:25:25 UTC 2022

[JDK-8285263](https://bugs.openjdk.org/browse/JDK-8285263) innocuously rewrote an anonymous class in `SecureClassLoader.getProtectionDomain` to a (capturing) lambda. Since this is called during early bootstrap this shows up as a regression across the board on all our startup and footprint tests.

Restoring the anonymous class drops no. of classes loaded on a Hello World test from 493 to 448 (macosx).
