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
explicitly. Both are enabled automatically if sphinx-build is found.

The man page will be installed as `<meson_mandir>/man8/flashrom.8` and
The html documentation in <meson_datadir>/doc/flashrom/html`.

The Makefile builds only the man-page format.

Increase the minimum version of meson from 0.53.0 to 0.57.0 to be
able to pass environment variables to the custom_target() command. That
is needed to pass the FLASHROM_VERSION to the documentation.
