Pull app / OS info out of GPUI, add Linux information, make fallible window initialization (#12869)

TODO:
- [x] Finish GPUI changes on other operating systems 

This is a largely internal change to how we report data to our
diagnostics and telemetry. This PR also includes an update to our blade
backend which allows us to report errors in a more useful way when
failing to initialize blade.


Release Notes:

- N/A
