* fix: don't expose nativeTheme in the renderer process (#20139)
Exposing these in the renderer didn't make sense as they weren't backed
by the same instance / value store. This API should be browser only
especially now that we have nativeTheme.themeSource. Exposing in
//common was a mistake from the beginning.

* fix: emit updated on NativeTheme on the UI thread to avoid DCHECK

* chore: add SetGTKDarkThemeEnabled(enabled) internal helper to allow dynamic theme selection on linux (#19964)
This is just a after-creation setter for the `darkTheme` constructor option. This is delibrately
a method and not a property as there is no getter.
* spec: remove leftover .only
