Enable jQuery validate on register/contribution forms

[mattwire]

Overview

This makes jQuery validate available by default on frontend contribution / registration forms. Any site with Stripe enabled has been using this for about a year now.

Partial from #16488

Before

jQuery validate not available on frontend forms by default.

After

jQuery validate available on frontend forms.

Technical Details

This activates jquery validation (client-side validation) for forms. Which does nothing by itself but allows you to run eg. CRM.$('#Main').valid() and get a true/false response, also fields will show a "field is required" message.

This has also been enabled via the Omnipay processor - I think at the time I wanted to make this change but went with the more precautionary approach. However, I think this has had analysis & prod testing & this point in the cycle is good timing.

Also jquery validate is better than the slow way....
