participant-integration-api: Move SeedService here. (#10261)

I don't see a reason why it's part of the participant state API, and
it definitely doesn't need to change between v1 and v2.

CHANGELOG_BEGIN
- [Integration Kit] The class ``SeedService`` has been moved from the
  *participant-state* Maven package to the *participant-integration-api*
  Maven package, under the Java package name
  ``com.daml.platform.apiserver`` to reflect its usage by the API
  server, not the participant state API. If you use this class directly,
  you will need to change your imports.
