[jdk23u] RFR: 8334560: [PPC64]: postalloc_expand_java_dynamic_call_sched does not copy all fields

[Richard Reingruber]

Hi all,

This pull request contains a backport of commit [13dce296](https://github.com/openjdk/jdk/commit/13dce296fc3924b269757ce1279c57afe18faeeb) from the [openjdk/jdk](https://git.openjdk.org/jdk) repository.

The commit being backported was authored by Richard Reingruber on 24 Jun 2024 and was reviewed by Matthias Baesken and Martin Doerr.

The fix passed our CI testing: JTReg tests: tier1-4 of hotspot and jdk. All of Langtools and jaxp. JCK, Renaissance Suite, and SAP specific tests.
Testing was done with fastdebug builds on the main platforms and also on Linux/PPC64le.

Risk is low. The change affects only PPC64 and the field that is changed is only read in the JVMTI implementation. Also the change includes a regression test.

Thanks, Richard.
