fix(ivs): Not a standard physical name pattern (aws#24706)

## Summary

- change physical name of Props to `<cfnResource>Name`  (e.g channelName)
- generate physical name by CDK if not present

## Why need this change

Because the alpha package `aws-ivs` does not follow standard CDK physical name conventions. 

CDK expects an auto-generated physical name to be used if the physical name is omitted. This will result in the "Use generated resource names, not physical names " of [Best practice](https://docs.aws.amazon.com/cdk/v2/guide/best-practices.html#best-practices-apps-names) can be complied with. However, the current `aws-ivs` package configuration does not follow that rule, so if omitted, the resource will be created without a physical name. Being created without a physical name is inconvenient for resource management, and many customers are forced to use physical names explicitly.
Also, the standard CDK naming convention for the physical name property should be of the form `<cfnResource>Name` like bucketName, but the IVS package is just `name` and does not conform to the standard.

## Why changes now
Resolving these issues would require breaking changes and should be resolved before migrating to the stable package.

## Related issues
Closes none.

BREAKING CHANGE: Renamed ChannelProps.name to ChannelProps.channelName
* Renamed PlaybackKeyPairProps.name to PlaybackKeyPairProps.playbackKeyPairName
* Channel now generates a physical name if one is not provided
* PlaybackKeyPair now generates a physical name if one is not provided
