[route53] Support for health checks

Currently the only way to define a health check or even to enable health checks for alias targets appears to be using `Cfn` resources instead of the higher level constructs.

### Use Case
Route53 health checks are commonly used for multi-region architectures, and not being able to create them is a little limiting

### Proposed Solution

* [ ] :wave: I may be able to implement this feature request

This is a :rocket: Feature Request

Start by locating the Route53 higher-level constructs and checking how they currently expose Cfn resources and alias targets. Compare the available AWS Route53 health-check capabilities with the construct APIs and their tests. Done means users can define health checks and enable them for alias targets without using Cfn resources.
