KAFKA-8471: Replace control requests/responses with automated protocol (#7353) 

Replaced UpdateMetadata{Request, Response}, LeaderAndIsr{Request, Response}
and StopReplica{Request, Response} with the automated protocol classes.

Updated the JSON schema for the 3 request types to be more consistent and
less strict (if needed to avoid duplication).

The general approach is to avoid generating new collections in the request
classes. Normalization happens in the constructor to make this possible. Builders
still have to group by topic to maintain the external ungrouped view.

Introduced new tests for LeaderAndIsrRequest and UpdateMetadataRequest to
verify that the new logic is correct.

A few other clean-ups/fixes in code that was touched due to these changes:
* KAFKA-8956: Refactor DelayedCreatePartitions#updateWaiting to avoid modifying
collection in foreach.
* Avoid unnecessary allocation for state change trace logging if trace logging is not enabled
* Use `toBuffer` instead of `toList`, `toIndexedSeq` or `toSeq` as it generally performs
better and it matches the performance characteristics of `java.util.ArrayList`. This is
particularly important when passing such instances to Java code.
* Minor refactoring for clarity and readability.
* Removed usage of deprecated `/:`, unused imports and unnecessary `var`s.
* Include exception in `AdminClientIntegrationTest` failure message.
* Move StopReplicaRequest verification in `AuthorizerIntegrationTest` to the end
to match the comment.
