This commit introduces open polymorphism support with Kotlin
Serialization in HTTP converters and codecs as a follow-up of gh-34410
which considers Kotlin Serialization as a Jackson/Gson/Jsonb equivalent
(it is not anymore configured before Jackson).
Closes gh-34433
Prior to this commit, Spring MVC and WebFlux would consider the
"kotlinx.serialization" JSON codecs and converters in addition to other
JSON alternatives like Jackson, Gson and Jsonb.
This would cause issues because while in most cases this library is only
involved if the type is annotated with "@Serializable", this is not true
for Java enums. In this particular case, the codec shadows Jackson and
causes issues.
This commit now considers kotlinx.serialization JSON support as an
alternative to Jackson. Just like Jsonb and GSON, this is only
auto-detected if Jackson is not present.
We received consistent feedback that kotlinx.serialization is popular in
Kotlin libraries and is often a transitive dependency. As a result, we
cannot consider its presence on the classpath as a strong enough signal
to configure it by default.
Closes gh-34410
If the Servlet container delegates a disconnected client error via
AsyncListener#onError, wrap it as AsyncRequestNotUsableException
for more targeted and consistent handling of such errors.

This commit ensures that `ContentDisposition` parses attributes like
"filename" and "filename*" in a case insensitive fashion, per RFC 6266.

Ensure the original instance is always the one returned no matter how
many times the HandlerMethod is re-created.
Make the constructor protected to allow subclasses to re-create the
HandlerMethod as the concrete subclass.
See gh-34375
Prior to this commit, the `HttpHeaders` class would provide constructor
variants where the instances are are backed by the existing headers
collection given as a parameter.
While such constructors are clearly documented and meant for internal
usage, there are cases where developers would like to copy the data from
an existing headers instance without being backed by the same collection
instance and thus, being mutated from some place else.
This commit introduces new factory methods `HttpHeaders.copyOf` for this
purpose. While this name aligns with some of the Java collections
factory methods, in this case the returned instance is not immutable, on
purpose. `HttpHeaders` does not extends `MultiValueMap` anymore and
shouldn't be seen as such.

This commit adds support for Kotlin properties in Spring WebMVC
controllers, supported for reasons explained in gh-31856, with
kotlinx.serialization converters.

We now look for the target exception types in cause chain as well,
but return false if we encounter a RestClient or WebClient
exception in the chain.

As of gh-33847, method and field introspection is included by default
when a type is registered for reflection.
Many methods in ReflectionHintsPredicates are now mostly useless as their
default behavior checks for introspection.
This commit deprecates those methods and promotes instead invocation
variants. During the upgrade, developers should replace it for an
`onType` check if only reflection is required. If they were checking for
invocation, they should use the new 'onXInvocation` method.
Closes gh-34239
