Tutorial fixes

Closes #73

Several tutorials were developed for Atta in the past, but they were quite outdated. All tutorials were migrated to the latest atta release, and bugs found in Atta were fixed. The bugs are described in #73.

You can try all these tutorials online: https://atta.brenocq.com/projects/brenocq-atta/tutorial

🔧 Changelog

• Fix
  • Atta static build would fail if project doesn't have CMakeLists.txt
  • Atta static build would fail if project uses FetchContent with name `resources
  • ImPlot3D was not being installed
  • The graphics textures (both OpenGL & Vulkan) were not being updated when the image resource was updated
  • The viewport's zoom was not being saved when using the OrthographicCamera
    • This was fixing by saving the OrthographicCamera's height into .atta
  • Fix wrong behavior of build.sh's --disable-vulkan flag
  • The gfx::FastRenderer was not working properly in OpenGL, textures were being rendered with a contant color.
    • It turned out that iNormal was being optimized out because it was not used in fastRenderer.asl. This was fixed by adding a small dependency between the output and the input normal.
