Update CloudEvent types (#1089)

* Updates to exported CloudEvent Types.

This commit makes several updates to the exported CloudEvent types:

* Billing types include a notificationType
  * [Link](https://github.com/googleapis/google-cloudevents/blob/main/proto/google/events/firebase/firebasealerts/v1/cloud_event_payload.proto#L132-L133)
* Crashlytics have more documentation on fields
* Storage has an exported `StorageEvent` which includes the bucket.
* Storage function api references `StorageEvent` to better match to expected output.
* Fixed NPE issue for Storage without Config
* Updated more signatures to optionally expect a bucket.
