S3 MFA-Delete and Object Lock support

I don't see how to enforce MFA Delete and Object Locking in an S3 Bucket.

I can't find MFA-Delete in CloudFormation, but ObjectLock is:

```
Type: AWS::S3::Bucket
Properties:
ObjectLockConfiguration:
ObjectLockConfiguration
ObjectLockEnabled: Boolean

```

### Use Case

Define Buckets with MFA-Delete and Object Lock enabled from the start.

### Proposed Solution

Add the properties to the S3.Bucket object.
Workaround: Doing it manually after creation.

### Other

Maybe it already exists, or another workaround exists, and I didn't find it. Thanks.

This is a :rocket: Feature Request

Start with the S3.Bucket object and the CloudFormation properties shown in the issue, checking how existing ObjectLock support is represented. Done means buckets can be defined with MFA-Delete and Object Lock enabled from creation, without the manual workaround described.
