Mitchell Hashimoto 54fe8e1885 macos: handled untrusted OSC8 hyperlinks more carefully (#13634) ...

OSC8 hyperlinks previously executed directly via the NSWorkspace opener
so a malicious application can just do whatever it wanted and trick the
user into opening something through Launch Services.

This PR notifies apprt of OSC8 hyperlinks so they can be handled
specially. In this PR, I added macOS-specific handling of OSC8 through a
variety of improvements:

  - Preview text is sanitized, so invisible Unicode characters now show.
- Questionable-looking URLs require confirmation to open, but a user can
confirm to open.
- Very questionable or definitely unsafe URLs are blocked with an alert
that only allows the user to copy the link. The alert also notifies the
user why.

This PR also adds an explicit `link-osc8` config (default true) that
users can use to disable osc8 completely.
