Subject: [PATCH v6 13/21] tools/docs: sphinx-build-wrapper: add an argument for LaTeX interactive mode

By default, we use LaTeX batch mode to build docs. This way, when
an error happens, the build fails. This is good for normal builds,
but when debugging problems with pdf generation, the best is to
use interactive mode.

We already support it via LATEXOPTS, but having a command line
argument makes it easier:

Interactive mode:
	./scripts/sphinx-build-wrapper pdfdocs --sphinxdirs peci -v -i
	...
	Running 'xelatex --no-pdf  -no-pdf -recorder  ".../Documentation/output/peci/latex/peci.tex"'
	...

Default batch mode:
        ./scripts/sphinx-build-wrapper pdfdocs --sphinxdirs peci -v
	...
	Running 'xelatex --no-pdf  -no-pdf -interaction=batchmode -no-shell-escape -recorder  ".../Documentation/output/peci/latex/peci.tex"'
	...
