Clip qq line

This PR aims to fix #6087.

It does so by preserving the slope and intercept as computed variables and using geom = "abline".

ggplot(mpg, aes(sample = displ)) +
  geom_qq() +
  geom_qq_line() +
  ylim(range(mpg$displ)) +
  coord_cartesian(clip = "off")

Look man, it is the default GD when using {reprex}. I've my own session setup with ragg. I make sure to setup a proper GD in the readmes that I write. I have an rstudio shortcut that is called 'raggprex' to the following code:

#+ setup, include=FALSE
knitr::opts_chunk$set(dev = "ragg_png")

#+ main

Which I can then follow up with the actual code to reprex. Sometimes I forget to use the shortcut. If we could just permanently set the GD to ragg in {reprex}, I would be a happy camper, but until such a time, I'll throw around some pixellated lines every now and then :p
