Moved DamlSubmission* into separate proto file [KVL-980] (#10362)

CHANGELOG_BEGIN
[Integration Kit] Moved definitions of `DamlSubmission` and `DamlSubmissionBatch` to a separate proto file under the package `com.daml.ledger.participant.state.kvutils.wire`. In case you are directly referencing these messages you will have to update your imports.
