cmake: speed up libcurl doc building again

This time limit the number of files per command to avoid exceeding
limitations of certain OS/shell envs.

Such known env is Windows with the `cmd.exe` shell, which features an
8K command-line length limit to this day.

Allowlisting `UNIX` to have no limit and using a limit of 200 for other
envs to be safe. If there is a way to detect `cmd.exe` and/or we know
which precise envs are sensitive to this, we can tweak these conditions
further.

Even with the low limit, this patch reduces external commands by 200x,
making builds much faster.

docs: ascii version of manpage without nroff

Create ASCII version of manpage without nroff

- build src/tool_hugegelp.c from the ascii manpage
- move the the manpage and the ascii version build to docs/cmdline-opts
- remove all use of nroff from the build process
- should make the build entirely reproducible (by avoiding nroff)

- partly reverts 2620aa9 to build libcurl option man pages one by one
in cmake because the appveyor builds got all crazy until I did

The ASCII version of the manpage

- is built with gen.pl, just like the manpage is
- has a right-justified column making the appearance similar to the previous
version
- uses a 4-space indent per level (instead of the old version's 7)
- does not do hyphenation of words (which nroff does)

History

We first made the curl build use nroff for building the hugehelp file in
December 1998, for curl 5.2.

cmake: rework options to enable curl and libcurl docs

Rework CMake options for building/using curl tool and libcurl manuals.

- rename `ENABLE_MANUAL` to `ENABLE_CURL_MANUAL`, meaning:
to build man page and built-in manual for curl tool.

- rename `BUILD_DOCS` to `BUILD_LIBCURL_DOCS`, meaning:
to build man pages for libcurl.

- `BUILD_LIBCURL_DOCS` now works without having to enable
`ENABLE_CURL_MANUAL` too.

- drop support for existing CMake-level `USE_MANUAL` option to avoid
confusion. (It used to work with the effect of current
`ENABLE_CURL_MANUAL`, but only by accident.)

cmake: speed up curldown processing, enable by default

- cmake: enable `BUILD_DOCS` by default (this controls converting and
installing `.3` files from `.md` sources)

- cmake: speed up generating `.3` files by using a single command per
directory, instead of a single command per file. This reduces external
commands by about a thousand. (There remains some CMake logic kicking
in resulting in 500 -one per file- external `-E touch_nocreate` calls.)

- cd2nroff: add ability to process multiple input files.

- cd2nroff: add `-k` option to use the source filename to form the
output filename. (instead of the default in-file `Title:` line.)
