Extend our Java OSGi library to have a version that works for Kotlin. Add a `protobuf_versioned_kt_jvm_library` that creates a bundle with the OSGi manifest and call that instead of `kt_jvm_library` for all our kotlin maven release targets.
Closes#18812
The default name for the rules_jvm_external.maven rule is "maven". When not set, it defaults to "maven". For root modules also using rules_jvm_external, the name clash causes a warning:
```
DEBUG: $TMP/external/rules_jvm_external~/private/extensions/maven.bzl:154:14:
The maven repository 'maven' is used in two different bazel modules,
originally in '<my_workspace>' and now in 'protobuf'
```
Summarizing @shs96c in [1]:
> The common maven repo name allows rulesets to contribute to the user's JARs.
> However, this implies that maven is for the end user, not for transitive
> dependencies. If a ruleset needs private dependencies, it should use a custom

Since protobuf is not contributing to user's JARs, we'll use a custom namespace. There's precedent for using a custom namespace for library modules:
- rules_jvm_external uses `rules_jvm_external_deps` instead of `maven`.
- rules_kotlin uses `kotlin_rules_maven` instead of `maven`.

Bazel 7 updated java_out.source_jars to return a Depset.
Release images are still on Bazel 6, but cloudtops were updated to Bazel 7 already.

Adds Automatic-Module-Name after it was lost during the maven-bazel migration (and subsequent re-addition of osgi bundle support).
Updates OsgiWrapper to support adding the Automatic-Module-Name header to the list of properties supported by the `osgi_java_library` rule.
