Added a phone_to helper method, on the style of mail_to and sms_to. (#36775)

* Added a phone_to helper method, on the style of mail_to and sms_to.

It creates an anchor tag with the href set to tel: *here your number*
which, when clicked on a mobile phone, or on a desktop with a supported
application, lets the phone app kick in, and it prepopulates it with the
phone number specified.
