feat: better cmake support (#21)

* feat: CMakeSettings.json * chore: remove visual studio stuff chore: move .clang-format to main directory * feat: new file structure, easier to implement as a submodule within existing projects * chore: we actually include some code now... * chore: remove prebuilt libraries (oops) * feat: new shader building script using cmake * chore: add debug postfix specifier * fix: forgot that windows builds use 4J_Render_PC for the render library * fix: didn't add the output directory (where shaders are saved to) to the include directories of 4J_Render
