1. Revert changes in setHeader from 5.2.9 that caused regression on self-copy.
2. Update copyHeaders/IfAbsent to ensure a copy of native headers.
3. Exit if source and target are the same instance, as an optimization.

Prior to this commit, references to `JsonGenerator` and
`ByteArrayBuilder` were not closed/released within codecs calls.
This prevents Jackson from reusing more efficiently shared memory
resources.
This commit properly closes/releases Jackson resources in Spring MVC,
Spring WebFlux and Spring Messaging codecs.
A benchmark on WebFlux codecs (in both single value/streaming mode)
shows significant throughput and allocation improvements for small
payloads.

Prior to this commit, developers could configure their WebClient to use
their custom `ExchangeStrategies`, by providing it in the
`WebClient.Builder` chain.
Once created, an `ExchangeStrategies` instance is not mutable, which
makes it hard for further customizations by other components. In the
case of the reported issue, other components would override the default
configuration for the codecs maxInMemorySize.
This commit makes the `ExchangeStrategies` mutable and uses that fact to
further customize them with a new `WebClient.Builder#exchangeStrategies`
`Consumer` variant. This commit is also deprecating those mutating
variants in favor of a new `WebClient.Builder#exchangeStrategies` that
takes a `ExchangeStrategies#Builder` directly and avoids mutation issues
altogether.

This commit refines Coroutines annotated controller support
by considering Kotlin Unit as Java void and using the right
ReactiveAdapter to support all use cases, including suspending
functions that return Flow (usual when using APIs like WebClient).
It also fixes RSocket fire and forget handling and adds related tests
for that use case.
Closes gh-24057

This commit allows single-value async producers for the values of
metadata entries in both the SETUP and for requests. The same is also
enabled for data in the SETUP frame.

Before this change an @MessageMapping could be matched to any RSocket
interaction type, which is arguably too flexible, makes it difficult to
reason what would happen in case of a significant mismatch of
cardinality, e.g. request for Fire-And-Forget (1-to-0) mapped to a
method that returns Flux, and could result in payloads being ignored,
or not seen unintentionally.
This commit checks @ConnectMapping method on startup and rejects them
if they return any values (sync or async). It also refines each
@MessageMapping to match only the RSocket interaction type it fits
based on the input and output cardinality of the handler method.
Subsequently if a request is not matched, we'll do a second search to
identify partial matches (by route only) and raise a helpful error that
explains which interaction type is actually supported.
The reference docs has been updated to explain the options.
Closes gh-23999
