Build .c files with C compiler (DEF-3084)

(LINK REMOVED)Today, we compile .c files with clang++, which enables other code checks.

EDIT: Also support .m files

Box2c was released. But it is C library. And defold can't build it :(

I think as a workaround it can be build and added as library? but for me it will be easy to keep code and build for every platform with defold extender.
