This commit represents the majority of the work necessary to upgrade Ghostty to use Zig 0.16.0. Key parts: * In addition to its previous responsibilities, the global state now houses state for global I/O implementations and the process environment. It is now also utilized in the main application along with the C library. Where necessary, global state is isolated from key parts of the implementation (e.g., in libghostty subsystems), and it's expected that this list will grow. * We currently manage our own C translation layer where necessary. In these cases, cImport has been removed in favor of the new external translate-c package. Due to fixes that have needed be made to properly translate the dependencies that were swapped out, as mentioned, we have had to backport fixes from the current translate-c package (and the upstream Arocc dependency). We will host this ourselves until Zig 0.17.0 is released with these fixes. * Where necessary (only a small number of cases), some stdlib code from 0.15.2 (and even from 0.17.0) has been taken, adopted, and vendored in lib/compat.
