[lworld] RFR: 8368939: [lworld] TestInliningProtectionDomain fails since jdk-26+11

[Damon Fenacci]

## Issue
`compiler/ciReplay/TestInliningProtectionDomain.java` for class `ProtectionDomainTestNoOtherCompilationPrivate` fails because it expects `bar()` not to be inlined but it gets inlined instead.

## Cause
`TestInliningProtectionDomain` checks that ciReplay inlining does not fail with unresolved signature classes. For class `ProtectionDomainTestNoOtherCompilationPrivate` it expects `Integer` in its signature to be unresolved but it is resolved instead. The reason for this is that in valhalla boxing classes are automatically added when registering a loader ([JDK-8364034](https://bugs.openjdk.org/browse/JDK-8364034) (and later [JDK-8364483](https://bugs.openjdk.org/browse/JDK-8364483)):
https://github.com/openjdk/valhalla/blob/708b4f92431df90c115dac840fb8194ec3aac3fe/src/hotspot/share/classfile/systemDictionary.cpp#L215-L217

## Fix
`TestInliningProtectionDomain` should actually use a different class than `Integer` (a class that is not in the migrated value classes set, like `java.lang.Thread`. Changed in all classes for "consistency").

## Testing
Tier 1-3
