Add all of the built in Angular form validation as a built in Incrudable validation

[dpsthree]

Validation was recently added to the forms API. To prove out this functionality, a built-in "required" validator was added. This was built on top of the same mechanism that developers can use to define their own custom validators. Its implementation can also serve as an example of how to add additional built-in validators.

Use the required validator as a template to add all of the built-in Angular form validators as built-in Incrudable form validators.
