Update publishing and usage of kotlin-annotation-processing plugin

- removed 'kotlin-annotation-processing-gradle' publication as it
duplicated 'kotlin-annotation-processing-embeddable'
- removed 'kotlin-annotation-processing-maven' as it is embedded into
  'kotlin-maven-plugin'. Instead 'kotlin-maven-plugin' now depends on
  'kotlin-annotation-processing' directly.
