docs: pdfdocs: Pull LaTeX preamble part out of conf.py
Quote from Jon's remark [1]:
I do notice that Documentation/conf.py is getting large and
unapproachable. At some future point, it might be nice to pull
all of the latex stuff out into a separate file where it won't
scare people who stumble into it by accident.
Pull LaTeX preamble settings added since commit
3b4c963243b1 ("docs:
conf.py: adjust the LaTeX document output") out into
sphinx/kerneldoc-preamble.sty.
It will be copied to the build directory by the added
"latex_additional_files" setting in conf.py.
As a bonus, LaTeX/TeX code can be maintained without escaping backslashes.
To compensate the loss of change history in sphinx/kerneldoc-preamble.sty,
here is a list of changes made in conf.py:
