This commit modifies the integration tests for the Maven and Gradle
image building goal and task to use a custom builder as a test harness
to verify that the plugins invoke the builder as expected.

Previously DataRedisTest-annotated test could not use reactive
operations as RedisReactiveAutoConfiguration is not considered. This
commit includes this auto-configuration and adds a test to exercise this
scenario.

Previously, users of the components.index could not use the index in
scenario where Spring Boot needs to locate the SpringBootConfiguration
to use to bootstrap the test context, as AnnotatedClassFinder scans
the classpath for that stereotype specifically and that requires a
dedicated entry for it.

This commit makes sure that a SpringBootConfiguration-annotated type has
a dedicated entry in the components index.

Closes gh-26308

This commit changes the Maven build-image goal to honor the `layout` and
`layoutFactory` parameters to ensure that the archive content sent to the
builder is the same as is used by the `repackage` goal to build the
archive file.

Previously, the targetJavaVersion property of bootBuildImage was set
using the project's target compatibility directly. This meant that
property's value would reflect the configured target compatibility at
the time of the task's creation and any subsequent changes to the
target compatibility would be missed.

This commit updates the registration of the bootBuildImage task to set
the value of the targetJavaVersion property using a provider. This
indirection means that the project's target compatibility isn't read
until the value of the targetJavaVersion is read, allowing any changes
to the target compatibility to be picked up even if they're made after
the bootBuildImage task has been created.

The previous workaround worked but prevented caching of every test
task as the value of system property pointing to the custom security
properties file varied from build to build.

This commit refines the workaround to copy the file into the build
directory of the test task's project and reference it using a URL
that's relative to the task's working directory. This ensures that
the value of the system property doesn't change from build to build.

Previously a number of file- or directory-based task inputs were
configured with specifying their path sensitivity. This meant
that the default absolute path sensitivity was used. For caches
that are cacheable this would result in a cache miss when the
inputs were identical other than being located at a different
absolute path as they are when running a CI build vs a local build.

This commit updates the configuration of additional task inputs
to use relative path sensitivity. A property name for each input has
also been configured. This makes them easier to identify in build
scans.
