Previously, SpringApplicationShutdownHook would call close() on any
registered application context even if it wasn't active as it had
already been closed. This could lead to deadlock if the context was
closed and System.exit was called during application context refresh.
This commit updates SpringApplicationShutdownHook so that it only
calls close() on active contexts. This prevents deadlock as it avoids
trying to sychronize on the context's startupShutdownMonitor on
the shutdown hook thread while it's still held on the main thread
which called System.exit and is waiting for all of the shutdown hooks
to complete.

Update `Instantiator` so that it can accept a `ClassLoader` when
creating instances and rework `EnvironmentPostProcessorsFactory` to
use the new methods.
Prior to this commit we would use the `ClassLoader` to get the class
names from `SpringFactories` but not when actually creating the
instances.
Fixes gh-27043
Update `RepackageMojo` and supporting classes so that `exclusions`
on the repackage goal apply to both the contributed libraries and any
existing jar entries already contained in the original war.
Prior to this commit, exclusions would apply to contributed jars (for
example, those in `WEB-INF/lib-provided`) but not jars that were
packaged directly into `WEB-INF/lib` by the war plugin

Prior to this commit, `NettyProperties` would use `DISABLED` as the
default level for leak detection in Netty. This is not the default value
enforced by Netty, which is `SIMPLE`.
This commit changes the default configuration property value and ensures
that both stay in sync.
