VSCode : Enable Development inside Docker Container

This will enable seamless Development of optee_client Project with VSCode
inside Docker container.

The VSCode Container provides:

* Automatic Mapping of the host user UID/GID inside the container
* Cross-Compilers (aarch64/armhf)
* GDB Multiarch for Debugging
* Remote SSH on the Target with seamless ssh mapping of the Host inside the container (Linux/Windows WSL)
* Git and Git Extensions to work and send Patches

Note: This require Docker installation for Linux/or Windows :
      [1] https://docs.docker.com/engine/install

      VSCode Extensions (extensions.json) will be recommended for the installation
