fix(lib): doom-plist-merge causing side-effects

Browse source 
This one was sneaky. `doom-plist-merge` was mutating the second plist
fed to it, causing issues upwind of its uses. In #7925, for example,
calling `doom-package-recipe` to read a package's recipe would end up
altering it, copying sub-properties of :recipe to other packages'
recipes.

If you've hit #7925, you'll also need to delete your build-cache to get
around the error. I.e.

  rm -f $EMACSDIR/.local/straight/build-*-cache.el
  doom sync  # or upgrade

Fix: #7925
