The last remaining Jenkins job prior to BK migration is for
exhaustive tests. The compatibility phase seems to be failing
since https://github.com/elastic/logstash/commits/57dc14c92
with Java 17.0.2
This commit switches from OpenJDK 17 (whose last release was 17.0.2)
to AdoptiumJDK 17 which actively receives updates and is bundled
in the custom images used by Jenkins.
Add ability to pull the version used to build java from the logstash repo, rather
than rely on system Java. Previously, builds would use JAVA_HOME, now this setting
is ignored in Logstash (and by extension, parts of the Logstash build), which was causing
variations in the version of Java used to build Logstash, including the use of Java 8,
which the Logstash team would like to remove support for.

This adds the .ci/matrix-runtime-javas.yml file that defines all
the JDKs logstash could be tested against. This is meant to be
used for the Matrix Combinations Jenkins plugin to be able to
select which JDK to test against dynamically.
To be unlinked from infra and made the selection of OSes that Logstash is tested against, the list is moved .ci specific yaml files.
By now the OSes are distinguished by Windows platform and by Linux distributions.
Separated selection of OSes in CI for compatibility and normal tests
