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.
