Previously, the default client and server HTTP message converter
customizers were ordered with lowest precedence. This made it
impossible to guarantee that another customizer would be able to go
after the default customizers, preventing their customizations from
being reliably overridden.
This commit updates the definitions of the default customizers to
order them at 0. This allows additional customizers to be ordered
either before or after them. Usage of the customizers is now always
ordered (previously Spring MVC's was not).

Create `spring-boot-resttestclient` and `spring-boot-webtestclient`
modules to hold test client auto-configuration and `TestRestTemplate`
code.
Previous these classes were contained in `spring-boot-resetclient-test`
and `spring-boot-webclient-test` which was incorrect since the `-test`
modules should hold code need to test the given modules, not supporting
test classes.

Prior to this commit, Spring Boot had an `HttpMessageConverters` class
that allowed, to configure message converter instances for MVC server
applications and traditional Spring HTTP clients.
As of Spring Framework 7.0, Framework ships its own
`HttpMessageConverters` class, aligning with the existing codecs
configuration on the WebFlux side. As a result, a few methods taking
`List<HttpMessageConverter>` as arguments were deprecated in favor of
the new arrangement.
This commit adapts to the Framework changes by deprecating Boot's
`HttpMessageConverters` in favor of Framework's. This splits the client
and server configuration as they are meant to be managed separately.
Applications can still contribute `HttpMessageConverters` (Boot's
variant) beans but the type itself is now deprecated.
Instead, applications should now contribute
`ClientHttpMessageConvertersCustomizer` and
`ServerHttpMessageConvertersCustomizer` beans to customize message
converters.
Closes gh-46411
This commit removes the "kotlin-serialization" option from the
`spring.http.converters.preferred-json-mapper` and configures the kotlin
serialization http message converter ahead of the preferred JSON
converter.
This effectively makes Kotlin Serialization a converter that is
considered first for JSON support, and then Jackson/Jsonb/Gson is
considered as fallback.
