* Remove usage of HandlerList and reduce usage of Handler.Collection
"The best part is no part" - Elon Musk!
The overwhelming usage of `HandlerList` and `Handler.Collection` was for adding the `DefaultHandler` after the main handler. This PR adds a getter/setter for a `DefaultHandler` on the server, so we no longer need to always create a `Handler.Collection` structure. This has allowed the deprecated `HandlerList` and `HandlerWrapper` classes to be removed.
In implementing this PR, several problems were found in the calculation of `InvocationType`, not least that it was assumed that an empty `Handler.Collection` was `BLOCKING`. When this issue was fixed, any dynamic addition of contexts (deployer or SPI server) failed as the `InvocationType` changed. So this PR also introduces the `isDynamic()` attribute of all `Handler.Container`s. A dynamic container will always return `BLOCKING` from `getInvocationType()`, as there is always a race with a new handler being added. A non-dynamic container will return a real `InvocationType`, calculated from its children, but it's mutator methods will ISE if contained handlers are changed.

* Fixes#8993 - Retainability of special Chunks
* Restored Jetty 11's AsyncContentProducer and related classes in jetty-ee9-nested module (src and test).
* Introduced Retainable.canRetain().
* Removed Chunk.isTerminal() and replaced it with alternative method calls.
* Clarified AsyncContent.write() in case of Chunk.Error.
* Removed AsyncContent.write(Chunk, Callback) because it was making the API confusing.
For example, AsyncContent.close() clashing with write(EOF, NOOP), or
AsyncContent.fail(x) clashing with write(Chunk.Error, NOOP), etc.
* Improved usage of Chunk.from(..., Retainable).
* Improved usage of Chunk.slice().
* Using from() in MultiPart, rather than duplicating code.
* Fixed MultiPart.Parser.Listener.onPartContent() javadocs.
* Renamed non-retaining Chunk.from() to Chunk.asChunk().
* Removed Chunk.slice() methods, inlining them where necessary.
* Carefully reviewed all usages of read()-like methods that return a Retainable instance to make sure it is released.
* Updated HTTP/2 and HTTP/3 usages of Stream.Data to follow the correct retain/release semantic.

* Reorganization of jetty-client classes.
* Moved oej.client.api to oej.client
* Moved oej.client.util to oej.client
* Moved implementation classes to oej.client.internal
* Moved transports to oej.client.transport
* Moved transport implementation classes to oej.client.transport.internal
* Moved TunnelRequest to oej.client.internal.
* Moved FastCGI transport classes to o.e.j.fcgi.transport
* Moved FastCGI transport implementation classes to o.e.j.fcgi.transport.internal
* Updated WebSocket core client to use only exported, non-internal, oej.client classes.
* Expanded oej.client.Destination APIs:
- added: getOrigin(), isSecure(), getProxy(), getConnectionPool(), getHttpClient(), send(..).
- removed: getScheme(), getHost(), getPort() because they don't uniquely identify a Destination anymore (Origin does)
* Moved destination sweeper functionality from HttpDestination to HttpClient.
HttpDestination does not implement close() anymore, now relies on LifeCycle.stop()
* Moved HttpReceiver.storeCookie() logic to HttpClient.putCookie() to avoid exposing CookieManager.
* Moved HttpClient.getAcceptEncodingField() to ContentDecoder.Factories
* Avoid public/protected Logger instances.

ResourceCollection should not have a path
Nor name, nor filename unless all resources agree on it.
revert combine and related methods to return Resource and not explicitly a ResourceCollection, as if there is only 1, then a collection is not needed
cleanup ResourceCollection creation. Avoid sanity checks on resolved resources.
* Restored interim responses functionality (100 Continue, 102 Processing, 103 Early Hints) for core, ee9 and ee10.
Added ProcessingProtocolHandler and EarlyHintsProtocolHandler for the client.
Re-enabled all tests for interim responses for all protocols.

* Adding Servlet 6 XML Entities
* Fixing bad xsi:schemaLocation entries
* Update all jetty-ee10 web XMLs to JakartaEE version 6.0 based
* Using XML Catalog
* Introducing catalogs for:
- default XML xsd/dtd (catalog-org.w3.xml)
- Configure dtd (catalog-configure.xml)
- EE10 Servlet 6 xsd/dtd (catalog-ee10.xml)
- EE9 Servlet 5 xsd/dtd (catalog-ee9.xml)
- EE8 Servlet 4 xsd/dtd (catalog-ee8.xml)
* New XmlParser.addCatalog(URI catalogXml, Class<?> classBase)
to allow the loading of a catalog which has it's resources
referenced via the classBase.getResource(name)
* WebDescriptor uses Environment to load appropriate catalog.
* Remove XmlParser.redirectEntity(String, String)
Made Chunk implement Retainable, and protocol implementations
to link the RetainableByteBuffer all the way to the Chunk.
Extended Retainable to have both a retain() and a release() methods.
Removed HTTP/2's ISession and IStream, now just using HTTP2Session and HTTP2Stream.
Removed *.Adapter classes in favor of interfaces with default methods.
Javadoc additions and clarifications.
