feat(fsx): add properties to enable automatic backups for Lustre file…

… system (#30343)

### Issue # (if applicable)

Closes  #30340.

### Reason for this change
Current LustreFileSystem class does not support automatic backups.


### Description of changes
Add properties equivalent to those of the L1 construct to the L2 construct.

* [automaticBackupRetentionDays](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws%5C_fsx.CfnFileSystem.LustreConfigurationProperty.html#automaticbackupretentiondays)
* [copyTagsToBackups](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws%5C_fsx.CfnFileSystem.LustreConfigurationProperty.html#copytagstobackups)
* [dailyAutomaticBackupStartTime](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws%5C_fsx.CfnFileSystem.LustreConfigurationProperty.html#dailyautomaticbackupstarttime)

Segregated the `dailyAutomaticBackupStartTime` as a class to enable its usage in another file system's L2 construct (for example, Ontap) in the future.



### Description of how you validated changes
Add unit tests and integ tests.
