TextMessage.getText() and ObjectMessage.getObject() may both return
null per the JMS specification when the message body was never set, but
SimpleMessageConverter.fromMessage() and its parent MessageConverter
interface currently declare a non-null return type despite residing in
an @NullMarked package.
To address that, this commit updates MessageConverter.fromMessage(),
SimpleMessageConverter, and the protected
extractStringFromMessage()/extractSerializableFromMessage() methods to
declare @Nullable accordingly and propagate the resulting nullability
through MessagingMessageConverter and
AbstractAdaptableMessageListener/MessageListenerAdapter, raising a
clear MessageConversionException where a non-null payload is required
by the Message<T> contract.

This commit introduces trusted packages, specified via the related
setter for untrusted use cases. It allows explicit configuration
of which Java packages are allowed to be deserialized.

Although this commit also changes the visibility of some test methods
to package-private, the remainder of that task will be addressed in
conjunction with gh-36496.

Prior to this commit, if the JmsClient was configured with a default
destination name (instead of a default Destination), invoking the
sendAndReceive() variant which accepts a map of headers resulted in an
exception stating that a default destination is required.
To address that, this commit overrides the
convertSendAndReceive(Object, Map<String, Object>, Class<T>, MessagePostProcessor)
method in JmsMessagingTemplate to add support for both a default
Destination and a default destination name.

This commit updates Jackson 3 JSON support to use JsonMapper
instead of ObjectMapper in converters, codecs and view constructors.
As a consequence, AbstractJacksonDecoder, AbstractJacksonEncoder,
AbstractJacksonHttpMessageConverter and JacksonCodecSupport are
now parameterized with <T extends ObjectMapper>.
Closes gh-35282
Prior to this commit, the `JmsTemplate` would use `MessagePostProcessor`
for mutating JMS messages before they are being sent, but only if the
method takes a post processor as an argument.
The main use case so far is to mutate messages after they've been
created by a `MessageConverter` from a payload.
This commit updates the `JmsClient` to use `MessagePostProcessor` more
broadly, for all outgoing messages (converted or not). This brings an
interception-like mechanism for clients to enrich the message before
being sent.
This change also updates the `JmsClient` static factories and
introduces a Builder, allowing for more configuration options: multiple
message converters and message post processors.
