Marshall Bowers d633a0da78 gpui: Fix Global trait (#11187) ... This PR restores the `Global` trait's status as a marker trait. This was the original intent from #7095, when it was added, that had been lost in #9777. The purpose of the `Global` trait is to statically convey what types can and can't be accessed as `Global` state, as well as provide a way of restricting access to said globals. For example, in the case of the `ThemeRegistry` we have a private `GlobalThemeRegistry` that is marked as `Global`: 91b3c24ed3/crates/theme/src/registry.rs (L25-L34) We're then able to permit reading the `ThemeRegistry` from the `GlobalThemeRegistry` via a custom getter, while still restricting which callers are able to mutate the global: 91b3c24ed3/crates/theme/src/registry.rs (L46-L61) Release Notes: - N/A		2024-04-29 16:37:37 -04:00
