MockMvc now properly detects the presence of an AsyncContext and
re-uses the response instance used to start it.
This commit also includes a minor fix in
ResponseBodyEmitterReturnValueHandler to ensure it does not disable
ETag related content buffering for reactive return values that do not
result in streaming (e.g. single value or collections).

Prior to this commit, the Resource `HandlerMapping` configured by
`@EnableSpringMvc` would be set up with only one custom
`HandlerInterceptor` (the one exposing the `ResourceUrlProvider` for
resolving URLs of static resources).
This behavior is not consistent with the rest of the default
configuration which leverages the interceptors configured against the
interceptor registry (with possible user-provided ones).
This change allows to register interceptors against resource handling;
this can be useful for metrics purposes, as in
spring-projects/spring-boot#10335.

The Javadoc on tag classes now has all the information including a
list of all tags at the package level, HTML tables listing tag
attributes in each tag class, and class level description that is
as good or in many cases better than what was in the reference.

Includes unified detection of Kotlin's optional parameters in MethodParameter.isOptional(), reduces BeanUtils.findPrimaryConstructor to Kotlin semantics (for reuse in AutowiredAnnotationBeanPostProcessor), and finally introduces a common KotlinDetector delegate with an isKotlinType(Class) check.

This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.
