Header files are now self-contained, which makes the relationships between the files clearer, and crucially allows LSP tools like `clangd` to function correctly in all of our header files. I have verified that the headers are self-contained (aside from the various Windows shims) by compiling them as if they were C files – in a follow-up commit I plan to add this to CI to ensure we don't regress on this front.
