Expose Finalizer String as Public Constant in AWS Controllers for Kubernetes Code Generator

[bugbuilder]

Is your feature request related to a problem?
It would be great to have the finalizerString exposed. This way, I wouldn't need to manually define the string, for example, "finalizers.route53.services.k8s.aws/HealthCheck", in my custom controller to check if the resource is already being managed, and then add my own finalizer. I have another custom controller that performs some logic after the resource is managed by ACK, and exposing this string would simplify the process.

Describe the solution you'd like
Capitalize finalizerString to FinalizerString in the AWS Controllers for Kubernetes code generator, making the finalizer string accessible across packages. This would allow external controllers to easily reference the finalizer without redefining it, ensuring consistency and reducing potential errors.

Describe alternatives you've considered
none

This is a great idea @bugbuilder - currently our finalizers aren't exported https://github.com/aws-controllers-k8s/s3-controller/blob/main/pkg/resource/bucket/descriptor.go#L30-L32 - would like to send a patch to the code generator? it should be a pretty simple addition. Happy to help if needed!
