Prior to this commit, we could only contribute `RuntimeHints` through
two mechanisms:
* `AotContributingBeanFactoryPostProcessor`, consdering the entire
`BeanFactory` and designed for contributing both code and hints.
* `AotContributingBeanPostProcessor`, consdering beans one by one, but
also designed for contributing both code and hints.
There are cases where libraries and applications want to contribute
`RuntimeHints` only, in a more static fashion: a dependency being
present, or a piece of infrastructure being considered by the
application context are good enough signals to contribute hints about
resources or reflection.
This commit adds the `RuntimeHintsRegistrar` contract for these cases.
Implementations can be declared as `spring.factories` and they will be
processed as soon as they're detected on the classpath. They can also be
declared with `@ImportRuntimeHints` and they will be processed if the
annotated bean definition is considered in the application context.
This annotation should be mainly used on configuration classes and on
bean methods.
```
@Configuration
@ImportRuntimeHints(CustomRuntimeHintsRegistrar.class)
public class MyConfiguration {
@Bean
@ImportRuntimeHints(OtherRuntimeHintsRegistrar.class)
public MyBean myBean() {
//...
}
}
```

This commit makes sure that TomcatServerHttpRequest::readFromInputStream
follows the same contract as the method it overrides, and returns
AbstractListenerReadPublisher.EMPTY_BUFFER when 0 bytes are read.

Previously, Graal failed to build a native image as DataSize was
unintentionally initialized at build time. This commit workarounds the
faulty assumption by flagging it as safe to initialize at build-time.
Closes gh-28328
This commit fixes a regression that added the Accept-Ranges header on
both client and server. Accept-Ranges is response header, so we now make
sure it only appears on the server side.

This commit updates BasicJsonWriter to handle TypeReferences and
generate an appropriate format for a class name. Specifically, an
inner class should be separated by a dollar sign, not a dot.
Closes gh-28312
This commit introduces explicit HEAD support in Spring
MVC's ResourceHttpRequestHandler and WebFlux's ResourceWebHandler,
adding just headers but no body.
Closes gh-28291
This commit ensures that any resources created for multipart handling,
obtained via ServerWebExchange.getMultipartData(), are automatically
deleted after handling the completing the response.
Resource for parts obtained via BodyExtractors::toMultipartData and
BodyExtractors::toParts are not cleaned automatically, and
should be cleaned via Part::delete.
