### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

copyObject and putObject (and perhaps other requests) requests are accepted and do not return an error when an SSE KMS key is specified. 

### Expected Behavior

The error which should be returned is KMS.NotFoundException.

### How are you starting LocalStack?

Custom (please describe below)

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

    Localstack testcontainers 

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

   Call copyObject/putObject via latest version using AWS SDK V2 and specific a ssekmsKeyId.

```java
final var copyObjectRequestBuilder =
        CopyObjectRequest.builder()
            .serverSideEncryption(ServerSideEncryption.AWS_KMS)
            .ssekmsKeyId("NON-EXISTENT KMS KEY")
            .sourceBucket(sourceBucketName)
            .sourceKey(sourceKey)
            .destinationBucket(destinationBucket)
            .destinationKey(destinationKey);
final var copyObjectResponse = sourceRegionS3Client.copyObject(copyObjectRequest); // Error should be thrown here but localstack does not return an error
```

### Environment

```markdown
- OS: MacOS 13.0
- LocalStack: Latest (v1.2.0)
```
