worktree: Don't open files >= 6GB in size (#27458)

Temporary Workaround For: #27283

This PR can (and should!) be reverted once the underlying inefficiencies
are resolved

Release Notes:

- Files that are 6GB or larger will now not open. This is a temporary
workaround for inefficient handling of large files resulting in
extremely high memory usage, often resulting in system freezing,
requiring a restart of Zed or the entire system.
