Adds the following new properties:
- spring.application.pid
- spring.application.version
Refactors the ResourceBanner and the structured logging support to use
the new properties.
Closes gh-41604
Prior to this commit, Spring applications and libraries would call
`Schedulers.boundedElastic()` or similar static methods at runtime. This
would ininitialize and cache reactive schedulers for the Reactor core
library. Those instances are cached for the lifetime of the JVM and are
shared static instances.
In a WAR deployment case, those schedulers would be initialized and
tied to the web application servlet context class loader. When
undeploying the web applications, schedulers would not be automatically
shut down and this would keep the now useless application classloader,
leaking resources.
This commit ensures that Spring Boot shuts down shared schedulers if
they were loaded and initiazed by the web application classloader, once
the the Spring application context is closed.
Closes gh-41548
Refine structured logging to support `Environment`, `ApplicationPid` and
`ElasticCommonSchemaService` injection. With these updates we are able
to remove the `ApplicationMetadata` class and simplify the parameters
passed to the layout/encoder classes.

This commit updates the auto-configuration to use the native connection
factory for configuring message listener containers. Previously, the
connection factory that could have been wrapped in a caching connection
factory was used.
While using a caching connection factory is suitable for sending
messages (i.e. JmsTemplate usage), it isn't for message listeners as
they need to own the connection for local recovery purposes.

Update Logback and Log4j2 integrations to support structured logging.
Support for the ECS and Logstash JSON formats is provided out-of-the-box
and the `StructuredLogFormatter` interface may be used to if further
custom formats need to be supported.

Add `JsonWriter` utility interface that can be used to write JSON
without the need for a third-party library.

Add `APPLICATION_NAME` and `APPLICATION_GROUP` properties that contain
verbatim values rather than formatted strings. Formatting of the values
is now handled by new `EnclosedInSquareBracketsConverter` classes for
both Logback and Log4J2.
The existing `LOGGED_APPLICATION_NAME` variable is now considered
deprecated. The `LOGGED_APPLICATION_GROUP` variable and related
logback converter have been removed since they never made it to a GA
release.

Any ProtocolResolvers that are registered in a spring.factories file
will be added to the application context using an
ApplicationContextInitializer.
