aws-fsx: L2 Constructs for DataRepositoryAssociation

### Describe the feature

Currently we have an L2 construct for [`LustreFileSystem`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_fsx.LustreFileSystem.html) but we are missing the L2 constructs for `DataRepositoryAssociation` ([`CfnDataRepositoryAssociation`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_fsx.CfnDataRepositoryAssociation.html)).

### Use Case

Use case is to create an FSx backed by an S3 bucket using a DRA. Currently its confusing since the `LustreFileSystem` L2 construct accepts the [`LustreConfiguration`](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_fsx.LustreConfiguration.html) which defines an `importPath` and `exportPath` but its not clear (or verified via the type system) that this cannot be used in conjunction with the DRA.

Docs: https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-properties-fsx-filesystem-lustreconfiguration.html

>This parameter is not supported for file systems with a data repository association.

### Proposed Solution

Create an L2 construct for DataRepositoryAssociation which validates that `importPath`/`exportPath` is not set on the `LustreFileSystem`. And make the documentation clear on how to set up a LustreFileSystem backed by an S3 bucket.
