Fixes for state storage env vars (#22191)

The current env var checks for state storage do not properly exclude empty env vars, as is currently implemented for log storage. This means that it is impossible to configure S3 state storage using both kustomize and helm, as those define env vars for the minio state storage (even when they are empty)
S3 state storage had two different env vars used for region

* check for empty env vars
* use consistent env var for STATE_STORAGE_S3_REGION
