[PATCH] doc/org-manual.org: Document `org-latex-src-block-backend'

[Ihor Radchenko]

Attaching tentative manual patch that explains about
`org-latex-src-block-backend'. There was no explanation about different
ways to export colored source blocks in the past.

Please try to read and let me know if anything is confusing.

+LaTeX export backend provides multiple ways to render src blocks in
+LaTeX, according to the value of ~org-latex-src-block-backend~:
+
+- =verbatim= (default) ::
+
+  Use =verbatim= LaTeX environment with no language-specific
+  fontification.
+
+- =listings= ::
+
+  Use =listings= environment provided by the corresponding LaTeX
+  package.  Org will not add the =listings= package to LaTeX preamble,
+  users need to customize ~org-latex-packages-alist~ or LaTeX headers
+  manually.
+
+- =minted= ::
+
+  Use more syntax-aware =minted= package.  Note that in addition to
+  customizing the LaTeX preamble, [[https://pygments.org][pygments]]
+  program should be installed and ~org-latex-pdf-process~ should pass
+  =-shell-escape= option to LaTeX executable.
+
+- =engraved= ::
+
+  Use =fvextra= LaTeX package and Emacs package
+  [[https://elpa.gnu.org/packages/engrave-faces][engrave-faces]]
+  available on GNU Elpa.  =engrave-faces= will use Emacs fontification
+  to colorize the source blocks in LaTeX output.

 The LaTeX export backend can make source code blocks into floating
 objects through the attributes =:float= and =:options=.  For =:float=:
