Allow `BeanDefinitionLoader` to load classes that don't have public
constructors. The constraint was first introduced in d82c50804f to
solve an issue with anonymous Groovy classes but causes particular
problems with `@SpringBootTest`.

Update `LaunchedURLClassLoader` so that packages defined from exploded
archive folders have manifest attributes applied to them. Prior to this
calling `package.getImplementationTitle()` would only return the a
manifiest attribute when running non-exploded.
The root cause of this issue is the way that `URLClassLoader` handles
the different URL types. For URLs that reference a jar the manifest is
available. For URLs that reference a folder it isn't. When running
exploded we use a URL that references to the `BOOT-INF/classes` folder
directly. To fix the issue we now attempt to detect when `definePackage`
is being called directly, and replace `null` entries with actual
manifest values.
Fixes gh-21705
Update `SpringBootServletInitializer` to use the `ServletContext` that
was provided to the initial `onStartup` call rather than the
one from the `ServletContextEvent`. This allows the `getClassLoader()`
call to complete without throwing an `UnsupportedOperationException`.

This commit improves the error messages returned by the Spring Boot
build plugins when a 5xx status code is returned from the Docker
API while attempting to build an image. If the error response has
contents containing a JSON structure with a "message" key, the value
associated with that key will be included in the exception message
and in the build plugin output error.
Fixes gh-21515
Update `SpringConfigurationPropertySource` so that wrapped random
property sources can be used. It's assumed that wrapped random
sources will use the name of the source as the prefix.
Closes gh-21595
Previously, if the Spring Boot build plugins got a connection error
when attempting to communicate with a Docker daemon (for example,
when the daemon isn't running), the error message made it appear that
the daemon returned an HTTP error code. This commit makes a connection
error distinct from an HTTP error response code to make it easier for
the user to diagnose the root cause of the problem.
Fixes gh-21554
