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`).

Issue: SPR-15407
This commit merges back the "spring-beans-groovy" module into the main
"spring-beans" one. The build is configured so:
* Java and Groovy sources are jointly compiled
* Kotlin sources are compiled after
With this change, the `MergePlugin` is not used anymore in the project
build and therefore is removed.
The `DetectSplitPackagesPlugin` wasn't applied so it's been removed as
well.
