feat(forms): Implement a way to manually set errors on a control

Example:

var login = new Control("someLogin");
c.setErrors({"notUnique": true});
expect(c.valid).toEqual(false);
expect(c.errors).toEqual({"notUnique": true});

c.updateValue("newLogin");
expect(c.valid).toEqual(true);

BREAKING CHANGE:

Before:

ControlGroup.errors and ControlArray.errors returned a reduced value of their children controls' errors.

After:

ControlGroup.errors and ControlArray.errors return the errors of the group and array.
And ControlGroup.controlsErrors and ControlArray.controlsErrors return the reduce value of their children controls' errors.

Closes #4917
