AtAjLTWTests: 4 test cases switched to 'useFullLTW' mode
After the Java 18 JDT Core upgrade, some LTW tests are failing and
have to be switched from in-process to full LTW mode due to them now
obviously calling some code paths which need '--add-opens'.

It was referring to a no longer existent weaver under
aj-build/dist/tools/lib/aspectjweaver.jar, which now has been replaced
by the new file lib/aspectj/lib/aspectjweaver.jar.
Several tests were broken, not finding the agent. But because those
tests make no assertions, nobody ever noticed. Only when I had to change
some LTW tests from in-process to full LTW mode (see next commit) due to
them now obviously calling some code paths which need '--add-opens', I
even noticed the problem.

Bump actions/setup-java from 1 to 3, use Temurin, drop Java 14
Adopt OpenJDK moved to Eclipse Temurin and is no longer updated. Temurin
builds for JDK 14 are however not available. Therefore, we drop the JDK
14 CI build.
Bumps [actions/setup-java](https://github.com/actions/setup-java) from 1 to 3.

Otherwise, Dependabot would run builds whenever something is pushed on
master and it rebases its PR. It is still possible to just click on the
skipped workflow in the PR and then issue "re-run all jobs" in order to
perform a build.

It will create PRs for Maven and GitHub action updates. Of course, we
cannot simply merge the PRs, because Dependabot has not singed an
Eclipse CLA, but at least we know about updates and how they affect the
build result. Then we can decide to clone the changes and commit them
manually.

Regression test for #125: Bugs198Tests.testGitHub_125
This test fails when run against AspectJ 1.9.8 with JDT Core 1.9.8.RC3.
It passes when using the latest JDT Core 1.9.9-SNAPSHOT. It sets system
property 'org.aspectj.weaver.openarchives=20', provoking open classpath
JAR file exhaustion when compiling a simple class with AJC, i.e. JARs
are being forcibly closed and automatically re-opened, as soon as they
are needed. Before the JDT Core bugfix, this test causes:
java.lang.NullPointerException
at ....compiler.batch.ClasspathJmod.getModulesDeclaringPackage
With the bugfix incorporated into AspectJ Tools, the problem is gone.
Note: New test dependency 'io.github.bmuskalla:scoped-system-properties'
helps to test compilation with the temporarily changed global system
property in isolation, saving the environment in a thread-local
variable and later cleanly restoring the original values again. If we
ever switch to parallel test execution, this would otherwise influence
other tests and potentially cause weird side effects. Better safe than
sorry.

Move some tests from Ajc198TestsJava to Bugs198Tests
They were accidentally stored in thw wrong test class, not just because
they are bug regression tests, not 1.9.8 features, but also because they
are meant to work on Java 5+, not on Java 17+ like the ones in
Ajc198TestsJava.

This fixes:
- negating annotation style if() pointcuts doesn't work
- annotation style if() pointcut not able to use a binding
that is not exposed
Fixes #120,#122
Fix annotation style support for if(true) and if(false)
The documentation specifies annotation style pointcuts
can use if(false) or if(true) and not require a boolean
return value and body for the @Pointcut annotated
method but it doesn't work without this change to validation
that recognizes the situation.
Fixes #115
Optimize class loading - make backward compatible with legacy behaviour
Now the defaults are:
+ org.aspectj.apache.bcel.useSingleRepositoryInstance (default: false)
+ org.aspectj.apache.bcel.useUnavailableClassesCache (default: false)
+ org.aspectj.apache.bcel.ignoreCacheClearRequests (default: false)
I.e. the new caching optimisations are opt-in instead of opt-out as
originally designed. This might change in the future, but for now
without any additional tests and experience with the new feature let us
be conservative and make the build green first.
I also added a few more code review findings concerning backward
compatibility, which was less than 100% even with all three flags
deactivated.

In our project we found out that during the build up of the spring context
the class loading takes a very long time.
Root cause is the huge amount of file I/O during pointcut class loading.
We are taking about ~250k file loads.
With these changes we managed to cut down the starting time by around 50%.
What we found out is that IMHO - the clear method of the ClassLoaderRepository
is called far too often -> in our settings this resulted in not a single cache
hit as the cache got cleared permanently.
Therefore we de-actived the cache clear calls inside the ClassLoaderRepository.
Secondly we changed the Java15AnnotationFinder in a way to not always create
new objects for the ClassLoaderRepository but re-use one static instance.
Otherwise we experienced >100k objects being created.
Last but not least we introduced a cache for unavailable classes so that
they do not have to be looked up using file I/O over and over again.
The whole behavior is configurable via
+ org.aspectj.apache.bcel.useSingleRepositoryInstance (default: true)
+ org.aspectj.apache.bcel.useUnavailableClassesCache (default: true)
+ org.aspectj.apache.bcel.ignoreCacheClearRequests (default: true)
