Subject: [PATCH] Add `NSCalibratedRGBColorSpace` support.

**Problems**

Ghostty is using sRGB by default, optionally Display P3 color space.
However neither color space matches to the color space that the regular
macOS apps are using.
That is `NSCalibratedRGBColorSpace`, seems called "Generic RGB" from
initializer API name.

Because of this, colors has same hex value are slightly darker on
Ghostty compare to Terminal.app, for example.

**Solution**

Add `generic-rgb` to `WindowColorspace`, therefore users can set
`window-colorspace` to `generic-rgb` in config to have similar colors
with the other macOS apps.
