[PATCH] Update c-ares for including config scripts for CMake

I compiled FlightGear Simulator for CYGWIN and MinGW and I dicovered
that the simgear component was not able to find c-ares library.

With reference to this message:
https://cygwin.com/pipermail/cygwin-announce/2025-December/012721.html
recently, c-ares has been updated to the latest version available at
the time of writing, but it has been compiled by using autotools.
As result, the development package does not include the config scripts
for CMake.

So, I updated the script for cygport of c-ares for using CMake instead.
Now, the development package also includes the config scripts for
CMake and simgear has been able to find the library successfully.

I cloned the sources of the existing package script here:
https://cygwin.com/cgit/cygwin-packages/c-ares/
and created a patch file that you can find attached to this email.

At this address:
https://github.com/carlo-bramini/packages-cygwin/tree/main/c-ares
you can also find the modified cygport file with my precompiled libraries.

The changes can be resumed as:
1) Added inherit to cmake
2) Increased release number from 0 to 1
3) Added CYGCMAKE_ARGS. Note, I have not removed autotools arguments
just to keep the patch smaller.
4) libcares_devel_CATEGORY is now "Devel".
5) I removed the man files from libcares_devel and I created a new
libcares_doc as "Doc".

Into the above address of my packages-cygwin repository, you can also
find updated packages for MinGW cross compilers, if you will want to
upgrade them too.

I hope that all you and the maintainer of the c-ares packages will
find this report useful.

Sincerely,

Carlo Bramini.
