fix(scheduler-targets-alpha): scope down permissions for sqs and kinesis stream targets (#32122)

### Issue # (if applicable)

Tracking #31785 

### Reason for this change

We want to enforce principle of least privilege when granting target actions to the scheduler execution role. From the Scheduler docs, only `kinesis:PutRecord` and `sqs:SendMessage` are required. Previously we were using built-in grant methods for these targets that granted additional permissions. If wider permissions are needed the user can always provide their own IAM role for the scheduler to use.

KMS permissions references from service docs:
- Kinesis stream: https://docs.aws.amazon.com/streams/latest/dev/permissions-user-key-KMS.html#example-producer-permissions
- SQS Queue: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-key-management.html#sqs-what-permissions-for-sse

### Description of changes

- Explicitly grant only the necessary target permissions
- If target uses customer-managed key for SSEKMS, grant key permissions to role as well

### Description of how you validated changes

- updated unit tests
- deployed stacks with SSEKMS targets and verified the scheduled actions succeed
