Handle default conflict error for direct dispatch method handles

[matthewhall2]

On x86 (or any platform with JitDispatchJ9Method enabled), there is an optimization in J9RecognizedCallTransformer::process_java_lang_invoke_MethodHandle_linkToStaticSpecial which directly dispatches the method handle. At the moment this is not an issue, but the fix for #20677 needs to change the extra field of the J9Method to J9_JIT_NEVER_TRANSLATE, which causes an Invalid JIT return address error in the stack walker. This is may be due to vm->initialMethods.throwDefaultConflict having no ROM method.

Dealing with this will likely also fix #21193, so opening this issue to discuss separately.
