Stephan Bergmann 81debfba86 Restrict macOS ARM64 to Java >= 17 
The commit message of e529461bcb "Enable JVM also
on macOS ARM64" had identified
<https://cdn.azul.com/zulu/bin/zulu17.0.63-ea-jdk17.0.0-ea.27-macosx_aarch64.zip>
"to work reliably now" while other (older Zulu) JVMs "have always crashed with
SIGBUS that smelled like our uses of pthread_jit_write_protect_np in
bridges/source/cpp_uno/shared/vtablefactory.cxx colided with corresponding calls
in the in-process JVM".  Those observations would be in line with
<http://openjdk.java.net/jeps/391> "JEP 391: macOS/AArch64 Port" only
implemented for Java 17 now (see
<dbc9e4b50c>
"8253795: Implementation of JEP 391: macOS/AArch64 Port").

So for macOS ARM64 assume that all OpenJDK variants (i.e., providing an empty
jvmfwk/distributions/OpenOfficeorg/javavendors_macosx_aarch64.xml) of at least
Java 17 (i.e., building on recent 3460c16d7f
"Make getVersionInformation always return a VersionInfo" and "change the
hardcoded '1.8.0' to '17' for just that one platform") work.

JVM Framework Wrappers

Wrappers so you can use all the Java Runtime Environments with their slightly incompatible APIs with more ease.

Used to use an over-engineered "plugin" mechanism although there was only one "plugin", called "sunmajor", that handles all possible JREs.

IMPORTANT: The <updated> element in vmfwk/distributions/OpenOfficeorg/javavendors_*.xml files should only be updated for incompatible changes, not for compatible ones. As stated in the commit message of https://gerrit.libreoffice.org/#/c/69730/ in LibreOffice gerrit:

javavendors_*.xml <updated> should not have been updated...

Changing <updated> causes jfw_startVM and jfw_getSelectedJRE (both jvmfwk/source/framework.cxx) to fail with JFW_E_INVALID_SETTINGS, which in turn causes functionality that requires a JVM to issue a GUI error dialog stating that the user must select a new JRE in the Options dialog. While that behavior makes sense if a JRE was selected that would no longer be supported by the modified javavendors_*.xml, it is just annoying if an already selected JRE is still supported. And a compatible change to javavendors_*.xml implies that an already selected JRE will still be supported."
