Since Spring Framework 4.3.0.RC2, a default embedded value resolver
has been registered with the bean factory when one is not otherwise
configured. This meant that placeholders in `@Value` would be resolved
with or without PropertyPlaceholderAutoConfiguration defining a
PropertySourcesPlaceholderConfigurer bean. However, placeholders in
bean definitions would only be resolved if a
PropertySourcesPlaceholderConfigurer was defined.
This commit updates PropertyPlaceholderAutoConfigurationTests to align
with this change in Framework. We now test that placeholders are
resolved in `@Value` annotations with or without the auto-configuration
and that placeholders in bean definitions are only resolved with the
auto-configured.

Previously, LifecycleAutoConfiguration would check the current context
and all of its ancestors for a lifecycle processor bean, only
configuring a custom processor if one was not found. Every context
has a lifecycle processor so this check meant that lifecycle processing
timeout could not be customized in any context with a parent.
This commit updates the auto-configuration to only check the current
context.
Closes gh-22014
Previously, Spring Boot's modules published Gradle Module Metadata
(GMM) the declared a platform dependency on spring-boot-dependencies.
This provided versions for each module's own dependencies but also had
they unwanted side-effect of pulling in spring-boot-dependencies
constraints which would influence the version of other dependencies
declared in the same configuration. This was undesirable as users
should be able to opt in to this level of dependency management, either
by using the dependency management plugin or by using Gradle's built-in
support via a platform dependency on spring-boot-dependencies.
This commit reworks how Spring Boot's build uses
spring-boot-dependencies and spring-boot-parent to provide its own
dependency management. Configurations that aren't seen by consumers are
configured to extend a dependencyManagement configuration that has an
enforced platform dependency on spring-boot-parent. This enforces
spring-boot-parent's version constraints on Spring Boot's build without
making them visible to consumers. To ensure that the versions that
Spring Boot has been built against are visible to consumers, the
Maven publication that produces pom files and GMM for the published
modules is configured to use the resolved versions from the module's
runtime classpath.

Prior to this commit, the welcome page support implemented in gh-9785
would override existing index views in both annotation and functional
variants.
This comes from the fact that the feature was implemented as a
`RouterFunction` configured in the main `RouterFunctionMapping` bean.
Due to ordering issues between mappings, this would override existing
application mappings in some cases.
This commit ensures that the welcome page `RouterFunction` is
contributed to the context in its own handler mapping, ordered after the
application ones.
Fixes gh-21909
