FORMs to support GET, POST, and AJAX

## Prerequisites

- [x ] I have searched for similar features requests in both open and closed tickets and cannot find a duplicate.

Tickets seem to be closed so I don't know if the Elementor people are reading them.

- [x ] The feature is still missing in the latest stable version of Elementor ( Elementor Pro. )

**What problem is your feature request going to solve? Please describe.**
We're just asking for basic FORM functionality, so that Elementor Forms give us the same functions that a basic HTML form would.

**Describe the solution you'd like**
Setting for form to allow us to choose the
Method (such as GET or POST)
instead of forcing it to be an Ajax-type of request.

As @trendco suggested:
A Selection Option in the Settings would be the perfect Solution:
Use AJAX (as it is in the Moment)
Use POST to Customer File
Use GET to Customer File
And everyone would be happy -:)

**Describe alternatives you've considered**
There is a bunch of suggested hooks and such that could be done, but this seems so basic that I don't see why it can't be implemented.
