lang: add cmakescript language (#5815)

Fixes #5502 

In this PR I make an early attempt to add the CMakeScript as a language
in compiler-explorer. I will be fantastic having this since CMake is one
of the most used build system. Having an cmake interpreter in the web
would probe truly useful for teams and individuals, it will be a
fantastic way to share snippets of cmakescript and show how they are
executed with different cmake versions.
