HHH-14693, HHH-10668 Move non-supported dialects to the hibernate-community-dialects artifact and add the SQLite dialect originally contributed by Vlad Mihalcea which was adapted for Hibernate 6. Also add HSQLDB, MySQL and Sybase ASE configurations and a CI job config

= Dialects
A dialect is a class that provides information about the specifics of a database and translators for the SQL dialect of the database.
== Supported dialects
Hibernate supports a wide range of dialects out of the box. The following is list of officially supported databases:
* Apache Derby
* Cockroach
* Google Spanner
* H2
* HSQLDB
* IBM DB2 LUW
* IBM DB2 iSeries
* IBM DB2 z/OS
* MariaDB
* MySQL
* Oracle
* PostgreSQL
* Postgres Plus
* SAP HANA
* SQL Server
* Sybase ASE
Usually, Hibernate supports at least the database version that is also still supported by the respective vendor.
In many cases though, Hibernate supports even older versions of the databases,
but the support for these versions is not guaranteed.
Apart from the Hibernate team supported dialects, there are also community dialects.
== Community dialects
As of Hibernate 6.0, the Hibernate team decided to provide a clear way forward for community contributed dialects.
The `hibernate-core` artifact had many legacy dialects before 6.0 that were only tested and maintained on a best effort basis.
More and more database vendors requested to integrate a dialect for their database and even provided a PR with a dialect,
but the Hibernate team didn't want to add new dialects for databases that might not have a wide adoption
or any automated testing into the `hibernate-core` artifact. Even though the dialect was supposedly maintained by the vendor,
the Hibernate team was burdened with reviewing questions, issues and PRs that relate to these dialects.
To give database vendors and the community a clear way forward, the Hibernate team decided to introduce a new artifact,
called `hibernate-community-dialects` which is the new home for dialects that are maintained by vendors or individuals.
Starting with Hibernate 6.0 the `hibernate-core` artifact will only contain dialects that are supported and tested by the Hibernate team.
All the legacy dialects are moved to the `hibernate-community-dialects` artifact to have a clear separation based on the quality of the dialect.
Issues with dialects in the `hibernate-community-dialects` are usually not considered by the Hibernate team,
as the community is responsible for providing fixes and improving the dialects for newer database versions or ORM capabilities.
== Requirements for moving to hibernate-core
If a database vendor wants their database dialect to be included in the `hibernate-core` artifact,
several requirements have to be fulfilled:
* The vendor must provide access to a dedicated database server that can be used for testing
* The vendor must provide contact details to at least one employee who is mainly responsible for the maintenance of the dialect
* The responsible employee of the vendor must actively monitor and react to failures of the testsuite against the respective database
* The responsible employee of the vendor must ensure the testsuite is configured correctly in order for it to succeed on the respective database
* If the responsible employee of the vendor leaves the company, the vendor must provide contact details to a new responsible employee
In case the responsible employee is unreachable for a longer period or issues with the dialect are not attended to in a timely manner,
the Hibernate team will move the dialect back to the `hibernate-community-dialects` artifact.
Get in touch with the Hibernate team on https://hibernate.zulipchat.com/#narrow/stream/132096-hibernate-user[Zulip]
if you want to request the move of your dialect to hibernate-core.

* Service which acts as a registry for named strategy implementations.
* <p/>
* Strategies are more open ended than services, though a strategy managed here might very well also be a service. The
* strategy is any interface that has multiple, (possibly short) named implementations.
* <p/>
* StrategySelector manages resolution of particular implementation by (possibly short) name via the
* {@link #selectStrategyImplementor} method, which is the main contract here. As indicated in the docs of that
* method the given name might be either a short registered name or the implementation FQN. As an example, consider
* resolving the {@link org.hibernate.resource.transaction.spi.TransactionCoordinatorBuilder} implementation to use. To use the
* JDBC-based TransactionCoordinatorBuilder the passed name might be either {@code "jdbc"} or
* {@code "org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorBuilderImpl"} (which is the FQN).
* <p/>
* Strategy implementations can be managed by {@link #registerStrategyImplementor} and
* {@link #unRegisterStrategyImplementor}. Originally designed to help the OSGi use case, though no longer used there.
* <p/>
* The service also exposes a general typing API via {@link #resolveStrategy} and {@link #resolveDefaultableStrategy}
* which accept implementation references rather than implementation names, allowing for a multitude of interpretations
* of said "implementation reference". See the docs for {@link #resolveDefaultableStrategy} for details.
