Prior to this commit, the reactive `MultipartParser` and `PartGenerator`
types were leaking memory at runtime in specific cases:
* many HTTP clients must send multipart requests to be parsed and close
the connection while uploading
* the `PartGenerator` must be configured to write file parts to
temporary files on disk
* concurrency, upload speed must be important to trigger cases where the
file system is not fast enough to consume incoming buffers
The `MultipartParser` parses and emits `BodyToken` to its sink
(here, the `PartGenerator`). By definition, Reactor's `FluxSink` when
created with `Flux.create(FluxSink)` will use a "buffer" strategy and
will queue emitted elements if they cannot be consumed.
Here, the cancellation signal does dispose internal states in the
`MultiPartParser` and `PartGenerator` but does not clear the internal
queue in `FluxSink`.
This commit ensures that an operation is registered to release buffers
on the discard event.

Prior to this commit, the `HttpEntityMethodProcessor` would create a new
`ServletServerHttpRequest` input message to parse the native Servlet
request, but would not reuse it for reading the request body using the
message converters.
In gh-32471, we applied a change that updates HTTP headers accordingly
when request parameters are read. But not reusing the input message
means that we are losing this update when instantiating the resulting
`HttpEntity`.
This commit ensures that `HttpEntityMethodProcessor` uses the input
message it just created when decoding the request body.
Fixes gh-36298
Prior to this commit, the "application/*+json" wildcard MIME type was
added to the list of supported MIME types in the JSON messaging
converter. This change wasn't fully reflected in the
`AbstractMessageConverter`, because only strict matching of type and
subtybe were considered.
This commit updates the `AbstractMessageConverter` to not only check the
type and subtype, but also check whether the supported MIME type
includes the one given as a parameter.

This PR optimizes the performance of NamedParameterUtils#buildValueArray by deferring the call to findParameter(declaredParams, paramName, i).
Changes: In the original implementation, findParameter was called for every parameter in the loop, regardless of whether the paramValue retrieved from paramSource was already an instance of SqlParameterValue.
Since findParameter involves iterating through the declaredParams list (or performing lookups), skipping this call when paramValue instanceof SqlParameterValue is true reduces unnecessary CPU cycles and memory access, especially for queries with a large number of parameters or long declaredParams lists.

Prior to this commit, the `Netty4HeadersAdapter` `MultiValueMapi#remove`
implementation would return an empty list if no value was present. This
is not consistent with other implementations.
This change ensures that `null` is returned for those cases.
