Ink and paper settings for built-in themes (re: #6059)

[teunbrand]

This PR reimplements #6059 due to a gnarly git history that I couldn't manage to resolve. The reasoning for this PR remains unchanged, but I'll post the examples again so that you can see that these are the same:

devtools::load_all("~/packages/ggplot2")
#> ℹ Loading ggplot2

p <- ggplot(mpg, aes(displ, hwy)) +
  geom_point()

p + theme_bw(ink = "dodgerblue")

p + theme_gray(paper = "orchid")

p + theme_light(ink = "white", paper = "black")
