feat(cloudfront): support gRPC for distribution (aws#32535)

### Issue # (if applicable)

Closes aws#32534.

### Reason for this change



CloudFormation supports `GrpcConfig` property to enable gRPC in `CacheBehavior` and `DefaultCacheBehavior`.

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-grpcconfig.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-cachebehavior.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-defaultcachebehavior.html

So it would be good to enable gRPC for CloudFront Distribution using L2.

### Description of changes



Add  `enableGrpc` property in `BehaviorOptions`.

### Description of how you validated changes



Both unit and integ tests.
