RFR: 8341194: [REDO] Implement C2 VectorizedHashCode on AArch64 [v2]

[Mikhail Ablakatov]

> Fix and redo [JDK-8322770](https://bugs.openjdk.org/browse/JDK-8322770) which got backed out in [JDK-8341197](https://bugs.openjdk.org/browse/JDK-8341197) due to test failures / jlink failure. Initial PR: https://github.com/openjdk/jdk/pull/18487.
> 
> Compared to the initial PR, this one eliminates a mismatch between the `arrays_hashcode()` template and stub. The template defined v0-v7 & v12-v17 as TEMP  registers but the stub used v8-v9 which were not on the list. Changing v8-v9 in the stub to v12-v13 eliminates this mismatch. Other changes in aarch64.ad  is just a cleanup as some registers on the list were not used by the stub at all anymore.
> 
> Following the discussion on [JDK-8341197](https://bugs.openjdk.org/browse/JDK-8341197), we've added a `make bootcycle-images` step to our local CI pipeline to verify that the issue is fixed.

  Ensure that the inline code and the stub use the same registers
