Upgrade to Jetty 11

[adamretter]

Requires Java 17 support to be merged first - https://github.com/eXist-db/exist/pull/4574 (and so at this time it contains all commits of that PR also).

• This required me to also release a new version of Apache XML-RPC which supports Jakarta 5 - https://search.maven.org/artifact/com.evolvedbinary.thirdparty.org.apache.xmlrpc/xmlrpc/5.0.0/pom
• This also required me to release an updated version of Milton WebDav which supports Jakarta 5 - https://search.maven.org/artifact/org.exist-db.thirdparty.com.ettrema/milton/1.8.1.3-jakarta5/pom

@reinhapa A lot of your comments are duplicated from https://github.com/eXist-db/exist/pull/4574 as this PR is stacked atop that one as it is required.

@dizzzz Where are you seeing that error?

@reinhapa If you have a moment... I cannot understand why I am getting the javadoc error in the Javadoc CI run, as theproject has no dependency on javax.servlet any more after switching to Jakarta. Any ideas?

At least the Ubuntu build, error last lines

@dizzzz I think that must be an old run, the current one is passing just fine.

As we learned from #4586 uploading smaller payloads encoded as multipart/form-data is not tested. This test should be added as part of this change to ensure this is still working.
