Adding C++ template (#644)

* Initial GCC container for Cpp, need to surpress request for port

* Adding test

* Initial GCC container for Cpp, need to surpress request for port

* Adding test

* Missed updated platform.ts

* Changing port to undefined so it doesn't prompt

* Changed name to C++, fixed tests

* removing unused type

Unneeded type, already using PlatformOS from platform.ts

* Removing another duplication...

* Fixing lint error
