Rename `ApplicationContextTester` and related classes to
`ApplicationContextRunner` and refactor existing tests to use correctly
named variables.

Previously, JsonContentAssert returns AbstractMapAssert from
extractingJsonPathMapValue. This could lead to type safety warnings
when calling one of the assert's methods with a generic varargs
parameter such as
contains(Entry<? extends Object, ? extends Object>...).
This commit replaces the use of both AbstractMapAssert and
AbstractListAssert with MapAssert and ListAssert respectively. These
classes use final methods and @SafeVargs args to prevent the
above-described problem from occurring.

Rename `ContextLoader` to `ApplicationContextTester` and provide
distinct subclasses for standard, web and reactive application contexts.
Context callbacks now return AssertJ compatible contexts, allowing
tests to run directly on context. For example:
context.run((loaded) -> assertThat(loaded).hasBean("foo"));
The returned context can now also represent a context that has failed
to start (meaning that the `loadAndFail` methods are no longer needed):
context.run((loaded) -> assertThat(loaded).hasFailed());
Configuration classes are loaded via the recently introduced
`Configurations` class. This means that the tester no longer needs to
be directly aware of auto-configuration concepts.
See gh-9634
Update `TestPropertyValues` so that it can also be used to update
system properties. Properties are set before the call is made and
restored to their previous value afterwards.

This commit applies what's been done in gh-9166 for WebFlux client and
server, but for the `WebTestClient` auto-configuration.
`WebTestClient` can be configured for mock or integration tests and this
change applies `CodecCustomizer` beans to the client being built.
Closes gh-9577
This commit adds ContextLoader, a test helper that configures an
ApplicationContext that is meant to simulate a particular
auto-configuration scenario.
The auto-configuration, user configuration and environment can be
customized. The loader invokes a ContextConsumer to assert the context
and automatically close the context once it is done.
Concretely, tests can create a shared field instance of that helper with
the shared configuration to increase its visibility and tune the context
further in each test.
If the context is expected to fail, `loadAndFail` allows to optionally
assert the root exception and consume it for further assertions.
This commit also migrates some tests to illustrate the practical use of
the helper
Closes gh-9634
Remove test-jar artifacts from Maven projects and relocate classes. The
majority of utilities now live in the `spring-boot-testsupport` module.
This update will help us to deploy artifacts using the standard Maven
deploy plugin in the future (which doesn't support the filtering of
individual artifacts).
