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.

This fixes a regression from #2454. In that PR, we added an error when
positional arguments are detected. I believe that's correct, but we
were silently relying on the previous behavior in the CLI commands.
This commit changes the CLI commands to use a new argsIterator function
that creates an iterator that skips the first argument (argv0). This is
the same behavior that the config parsing does and now uses this shared
logic.
This also makes it so the argsIterator ignores actions (`+things`)
and we document that we expect those to be handled earlier.
