Provides a non-null guarantee for MethodMatcher's targetClass argument and strict separation between IntroductionAwareMethodMatcher and regular MethodMatcher, enabling DefaultAdvisorChainFactory to defer its IntroductionAdvisor determination until encountering an actual IntroductionAwareMethodMatcher (even behind union/intersection).

This involves a new ResourceTransactionDefinition variant that JpaTransactionManager indicates a transaction-local EntityManager on. HibernateJpaDialect uses this indicator for hard read-only behavior.

Reorganize imports to ensure consistent ordering. This commit also
expands any `.*` static imports in favor of using fully-qualified
method references.
Issue: SPR-16968
Update all classes so that inner classes are always last. Also
ensure that utility classes are always final and have a private
constructor and make exceptions final whenever possible.

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.
