emacs: Support font-locking.
Avoid breaking highlighting after adding new font-lock keywords. * emacs/guix-base.el (guix-insert-package-strings): Use 'propertize' instead of 'guix-get-string'. * emacs/guix-info.el (guix, guix-action, guix-file, guix-url, guix-package-location, guix-package-name): New button types. (guix-info-insert-action-button, guix-info-insert-file-path, guix-info-insert-url, guix-package-info-insert-location, guix-package-info-insert-full-names, guix-package-info-insert-non-unique-text): Adjust for 'guix-insert-button' and button types. (guix-package-info-name-button): New face. (guix-package-info-define-insert-inputs): Use it. Add new button types. (guix-package-info-insert-full-name): Remove. * emacs/guix-utils.el (guix-get-string): Replace 'face' with 'font-lock-face'. (guix-insert-button): Adjust for using button types.
