WELD-2722 Reintroduce incontainer testing to PRs

[manovotn]

JIRA issue - https://issues.redhat.com/browse/WELD-2722

There are expected failures due to at least:

• Fix PersistenceContextInjectionTest to include AutoCloseable as type … jakartaee/cdi-tck#381
• The need for new TCK to land in Central (4.0.4)
• WELD-2721 Change AfterBeanDiscoveryImpl to correctly check the state … #2746
• Address removal of managed beans/faces in jsp jakartaee/cdi-tck#374

Other adjustments are needed in probe tests, servlet containers and presumably even tests-arquillian (those that are integration only?).
I will incrementally fix any failures I encounter and update this PR accordingly.

Also, WFLY seems to have merged EE 10 deps into its main build (instead of just preview) so we might be able to consume that instead.

The TCK failure is currently not reproducible locally and looks like some timing issue.
The incontainer failures are related to servlet testing and will need updates of API, core and Arq. tomcat container.

#2750 has the changes I sent a diff for just for reference.

With recent push, I am able to get servlet tests pass with Tomcat

Recent failures in serialization tests are linked to wildfly/wildfly#15425

There are new serialization-friendlier classes used in WFLY and this causes CNFE for our serialization smoke tests.
This is because the new classes reside in WFLY's clustering module and we don't have access to the CL that loaded them from tests. I have yet to figure out how to bypass that.

Can you verify that wildfly/wildfly#15686 solves the problem?

[manovotn]

Dropped a comment into your PR, it almost does the job :-)

[manovotn]

Recent changes in wildfly/wildfly#15686 make the serialization tests pass again.
Once that PR gets merged, we should be able to get a green pass here as well (using nightly build of WFLY preview).

[manovotn]

This PR now contains updates to docs WRT to servlet support.
WFLY PR has been merged, so starting tomorrow we should again have relevant CI results on PRs.

[manovotn]

We are mostly green once again.
The failing TCKs seem flaky and I have seen them before (timeout interceptor tests). Locally they passed, so I'll have to look into those separately but they are definitely non-blocking.
