Improve cloudwatchevent_rule exception handling (#30823)

* Fix cloudwatchevent_rule exception handling

Where it is currently present, this change fixes the exception handling.
However, there are many places that it is lacking.

Fixes #30806

* Add new exception handling for cloudwatchevent_rule

Ensure all API calls are wrapped with exception handling

* PEP8 tidy up

* Remove unnecessary HAS_BOTO3 import and checks

Tidy up documentation so that NO_QA can be removed
