[XL] Change in flashrom[master]: move manpage to sphinx

[Thomas Heijligen (Code Review)]

Hello build bot (Jenkins), Edward O'Callaghan,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/flashrom/+/72619

to look at the new patch set (#7).

Change subject: move manpage to sphinx
......................................................................

move manpage to sphinx

Use sphinx (sphinx-doc.org) to generate the UNIX man page from an
reStructuredText file instead of dealing with plain groff.

Use `meson setup -Dman-pages=enabled ...` to build the man page,
and `meson setup -Ddocumentation=enabled ..` to build the web
documentation. Both are enabled automaticly if sphix-build is found.

The install paths are `share/man/man8/flashrom.8` and
`share/doc/flashrom/index.html`

The Makefile builds only the man-page format.
