Update the samples and tests to use the more idiomatic static import
style.

Relocate spring-javaformat plugins to the root of the project.

Closes gh-13306

Update `ConfigFileApplicationListener` to correctly load properties
that have `spring.profiles` values containing a list.

Prior to this commit the loaded would attempt to add the same document
twice resulting in a "property source cannot be added relative to
itself" error.

Closes gh-13362

Update `ConfigFileApplicationListener` to ensure that a
`spring.profiles.include` property that refers to an already processed
profile doesn't cause an infinite loop.

Closes gh-13361

Update `ConfigFileApplicationListener` so that `spring.profiles.include`
properties do not override higher priority active profiles.

This commit also changes when profiles get added to the environment.
Profiles are now added to the environment at the time of profile
processing so that they get logged in the order that they are processed.

Fixes gh-13273

Add test dependencies for saaj-impl and jax-ws since Java 9+ no longer
includes them.

Closes gh-12659

Update `InetAddressFormatterTests` to ensure that DNS resolvers that
return a "help" page for missing domains don't cause the build to fail.

As of Spring Framework 5.1, we're depending on the Reactor Californium
release train.
Reactor Netty is now at version 0.8 and changed its artifact
coordinates, package names and broke several APIs. Spring Framework is
now up-to-date with those changes and this commit does the same for
Spring Boot.

Note that in that process, the `NettyServerCustomizer` has been changed
since the former `HttpServerOptions.Builder` API is now gone from
Reactor Netty, and we're now relying on immutable server instances
instead of a stateful builder pattern.

Previously, WebMvcTags would fall back to using the request’s path
info if Spring MVC’s best matching path pattern attribute was not
available. For non-Spring MVC web frameworks that support path
variables, such as Jersey, this led to an explosion of URI tags that
could exhaust the heap.
