* Works for binary and text files. * Makes EditorQuickOpen work with custom resources again. * Information is cached and easily accessible. Properly fixes #66179. Supersedes #66215 and supersedes #62417 **WARNING**: This required breaking backwards binary compatibility (.res and .scn files). Files saved after this PR is merged will no longer open in any earlier versions of Godot.
