Create a "TLS driver" compatible with TotalCross to be implementation agnostic

[jeffque]

Is your feature request related to a problem? Please describe.

Create a driver in the likes of the vtls used in cURL.

The idea is that any vendor software coul be integrated inside TotalCross providing a custom settings of a structure

Describe the solution you'd like

The first step would be to become completly independent of vendoring axtls source, just creating a virtual tls driver for axtls such that it could be futurely swapped by any tls implementor. This tackles #330 and gives a way to solve to solve the issue gitlab/Totalcross/totalcross#654

Devices

All. Most importantly for those who are building their own flavored TotalCross.

Additional context

Enabling future compatibility with cipher and vendor interchange. Decoupling the VM code from the library itself.

This issue here does not tackle completly issue gitlab/Totalcross/totalcross#654, but opens the door for using other tls libraries available.
