[jdk21u] RFR: 8316304: (fs) Add support for BasicFileAttributes.creationTime() for Linux

[Severin Gehwolf]

Please review this backport of adding creation time support on Linux where the filesystem supports it. The patch is not clean, since the JDK 22 uses JEP 454 features in the test. I've rewritten the test to use JNI instead so as to avoid using `@enablePreview` in the test. Otherwise, the patch is identical to the head version.

Testing:
- [ ] GHA (still running)
- [x] nio tests (all pass)
- [x] Build tests on all major Linux architectures and Mac OSX, AIX so as to cover some of the unix branches. All good.
