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
