Introduces getBeanProvider(Class) and getBeanProvider(ResolvableType), also narrowing getBean(String, Class) and isTypeMatch(String, Class) to a non-null Class argument and enriching NoUniqueBeanDefinitionException with a full ResolvableType. In addition, ObjectProvider supports iterable/stream access for collection-style resolution of multiple matching beans now, and collection injection falls back to an empty collection in a single-constructor case with non-null arguments.

This commit includes an optimization of BeansUtils#instantiateClass
that favors Java reflection for default constructors before leveraging
Kotlin one for finding primary constructors and avoids Kotlin related
conditions when running in Java.
Issue: SPR-17069
This revision limits serializability of derived interfaces, superclasses and type parameters, optimizing for introspection performance instead.
Issue: SPR-17070
Allows for skipping the now-deprecated postProcessPropertyValues callback with its expensive PropertyDescriptor retrieval requirement. RequiredAnnotationBeanPostProcessor (which is dependent on postProcessPropertyValues) and the @Required annotation itself are also deprecated now: in favor of constructor injection (or afterPropertiesSet).
Issue: SPR-16918
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.

After the Groovy 2.5 upgrade, the Spring Framework build on JDK9 hit
GROOVY-8631. Adding the relevant `jax-api` dependency to the module
didn't fix this issue. The Groovy release notes mention the use of the
`--add-modules` JVM flag, but this is not an option for this build which
should run on JDK8 -> JDK11.
This commit changes the dependency from `groovy-all` to more focused
dependencies on Groovy in the `spring-beans` and `spring-context`
modules. This change seems to avoid the automatic loading of Groovy
enhancements to JAXB (shipped with `groovy-xml`).

Prior to this commit, a YAML entry that define an empty array value was
lost. This commit makes sure to flag it with an empty String, which
corresponds as an empty comma separated list of entries in the
properties format.
