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.

* jacoco/ coverage shouldn't trigger all test tasks as dependencies - instead, it should run after those test tasks that you choose to run. removed java plugin from top-level.
* Make coverage depend on the default test task.
* Update jacoco log plugin so that it doesn't make hard dependencies on test tasks.

Currently, this task is too silent and just writes HTML reports. It is a
nice improvement to print the summary to the console.
Before:
```
> Task :lucene:analysis:icu:jacocoTestReport
Code coverage report at: /home/rmuir/workspace/lucene/lucene/analysis/icu/build/reports/jacoco/test/html.
```
After:
```
> Task :lucene:analysis:icu:jacocoTestReport
Code coverage report at: /home/rmuir/workspace/lucene/lucene/analysis/icu/build/reports/jacoco/test/html.
> Task :lucene:analysis:icu:jacocoLogTestCoverage
Test Coverage:
- Class Coverage: 100%
- Method Coverage: 87.9%
- Branch Coverage: 82.7%
- Line Coverage: 92.8%
- Instruction Coverage: 92.7%
- Complexity Coverage: 78.8%
```
* Upgrade several build dependencies.
* Update error prone rules (those are off but they do trigger warnings/ errors)
* A few corrections I made before I turned off new warnings. Let's do nother issue to fix them.
In a previous commit, we updated HNSW merge to first write the combined segment
vectors to a file, then use that file to build the graph. This commit applies
the same strategy to flush, which lets us use the same logic for flush and
merge.
