zed: Add --system-specs arg (#27285)

Adds the `--system-specs` flag to the Zed binary, so that users who wish
to report issues can retrieve their system specs, even if Zed is failing
to launch

Still TODO:
- [x] Test and do best effort GPU info detection on Linux
- [ ] Modify GitHub issue templates to tell users that the flag is
available if they are unable to launch Zed

Release Notes:

- Added the `--system-specs` flag to the Zed binary (not the cli!), to
retrieve the system specs we ask for in GitHub issues without needing to
open Zed
