Mitchell Hashimoto 260e6dea59 macOS: fix theme reloading (#9360)
### Background
After #9344, the Ghostty theme won't change after switching systems',
and reverting #9344 will bring back the issue it fixed.

The reason these two issues are related is because the scheme change is
based on changes of `effectiveAppearance`, which is also affected by
setting the window's `appearance` or changing
`NSAppearance.currentDrawing()`.

### Changes
Instead of observing `effectiveAppearance`, we now explicitly update the
color scheme of surfaces, so that we can control when it happens to
avoid callback loops and redundant updates.

### Regression Tests

- [x] #8282
- [x] Reloading with `window-theme = light` should update Ghostty with
the default dark theme with a dark window theme (break before
[#83104ff](83104ff27a))
- [x] `window-theme = light \n macos-titlebar-style = native` should
update Ghostty with the default dark theme with a light window theme
- [x] Reloading from the default config to `theme=light:3024
Day,dark:3024 Night \n window-theme = light`, should update Ghostty with
the theme `3024 Day` with a light window theme (break on
[#d39cc6d](d39cc6d478))
- [x] Using `theme=light:3024 Day,dark:3024 Night`; Switching the
system's appearance should change Ghostty's appearance (break on
[#d39cc6d](d39cc6d478))
- [x] Reloading from `theme=light:3024 Day,dark:3024 Night` with a light
window theme to the default config, should update Ghostty with the
default dark theme with a dark window theme
- [x] Reloading from the default config to `theme=light:3024
Day,dark:3024 Night \n window-theme=dark`, should update Ghostty with
the theme `3024 Night` with a dark window theme
- [x] Reloading from `theme=light:3024 Day,dark:3024 Night \n
window-theme=dark` to `theme=light:3024 Day,dark:3024 Night` with light
system appearance, should update Ghostty from dark to light
- [x] Reload with quick terminal open
