This commit adds the `AutoConfigurationImportsAnnotationProcessor` to
the `spring-boot-autoconfigure-processor` annotation processor
module. When added to a project build, the annotation processor will
generate the
`org.springframework.boot.autoconfigure.AutoConfiguration.imports`
file automatically from `@AutoConfiguration`-annotated classes. It
also applies the annotation processor to the Spring Boot build.
Closes gh-31228
Test slices are now longer registered in spring.factories, but
TestSliceMetadata still looked there for them to generate documentation.
Fixed this so that TestSliceMetadata now looks in the right places for
test slices.

Implements a new AutoConfigurationLoader, which loads
auto-configurations from a file in META-INF/spring-boot.
Adapts the AutoConfigurationImportSelector to use the new loader.
Adapts the ImportAutoConfigurationImportSelector to use the new loader.
Adapts the metadata plugin in the build to additionally load the
auto-configurations from the new file.
Updates the documentation for auto-configurations and test slices.
Closes gh-29872
This annotation can be used to mark auto-configurations with a dedicated
annotation. Under the hood, it's a standard @Configuration with
proxyBeanMethods set to false.
Closes gh-29870
This involved a small code change to the generated configuration
properties snippets. The section id has to start with
'appendix.', otherwise the section-id asciidoctor extension
complains. To ensure that the anchors that are derived from the
section IDs remain backwards compatible, the anchor-rewrite
properties have been updated.
