This commit enables the Panama Vector API for Java 21. The version of
VectorUtilPanamaProvider for Java 21 is identical to that of Java 20.
As such, there is no specific 21 version - the Java 20 version will be
loaded from the MRJAR.
Leverage accelerated vector hardware instructions in Vector Search.
Lucene already has a mechanism that enables the use of non-final JDK APIs, currently used for the Previewing Pamana Foreign API. This change expands this mechanism to include the Incubating Pamana Vector API. When the jdk.incubator.vector module is present at run time the Panamaized version of the low-level primitives used by Vector Search is enabled. If not present, the default scalar version of these low-level primitives is used (as it was previously).
Currently, we're only targeting support for JDK 20. A subsequent PR should evaluate JDK 21.

* pass jvm args to javac #11925
* Update net.ltgt.errorprone to the latest version so that jvm args are not overwritten, add -XX:+PrintFlagsFinal for debugging
* speed up the pure javac case too
It does not help to fork additional VMs (although error-prone will do
this since it messes with bootstrap classpath), so we avoid forking.
Instead it is best to tune org.gradle.jvmargs.
* use the flags consistently everywhere (tests and doc)
* handle the different possible alt toolchain cases
The difference is invoking 'java' versus invoking 'javac', so the args must be fed differently.

This uses Gradle's auto-provisioning to compile Java 19 classes and build a multi-release JAR from them. Please make sure to regenerate gradle.properties (delete it) or change "org.gradle.java.installations.auto-download" to "true"

* use auto generate scripts to add comment
* update checksum
* update checksum
* restore toDot
* add removeDeadStates in levAutomata

* Bump %unicode 9 -> %unicode 12.1 for the 3 unicode grammars
* regenerate emoji conformance tests for unicode 12.1
* modify wordbreak conformance tests to use emoji data (which replaces old crazy E_base etc properties)
* regenerate wordbreak conformance tests
* Simplify grammar files and word-break conformance test generator, now that full-width numbers are WordBreak=Numeric
* Use jflex emoji properties rather than ICU-generated ones
Upgrade jflex.
Change doesn't alter the behavior of any of the analyzers (unicode
version or grammar refactorings), just the minimal to get new tooling
working.
Most cases of C-style array declarations have been switched. The Google Java Format, that which we adhere to, disallows C-style array declarations: https://google.github.io/styleguide/javaguide.html#s4.8.3-arrays
Some cases (esp. Snowball) can't be updated.
* LUCENE-9909: Some jflex regeneration tasks should have proper dependencies and also check the checksums of included files.
* Force a dependency on low-level spotless tasks so that they're always properly ordered (hell!). Update ASCIITLD and regenerate the remaining code. Add cross-dependencies between generation tasks that take includes as input.
The compilation of the library is slow, disable optimization as it doesn't speed up our usage of the gennorm2 tool.
Use better heuristic for make parallelism (tests.jvms rather than just hardcoded value of four).
Add a simple regeneration help doc
Improve task help and checksum failure message (include corresponding regeneration task). Sorry for being verbose. Maybe somebody will read it. :)

This adds a bit of simplicity as the file is a simple domain list,
rather than a DNS zone. So the regexes parsing DNS can be removed.
Also the file may change less often as it contains JUST the list of
TLDs, and not any additional DNS metadata.
