Add cygwin package information

[mkoeppe]

As a followup to #29053, in analogy to the work done for debian/fedora/arch/conda, we
add files build/pkgs/SPKG/distros/cygwin.txt to keep track of equivalent distribution packages

using these sources:

• https://github.com/sagemath/sage-windows/blob/master/cygwin-sage-build.list
• https://github.com/sagemath/sage-windows/blob/master/cygwin-sage-runtime.list
• https://trac.sagemath.org/wiki/Cygwin64Port

Follow-up: #29295 - Add GitHub CI workflow for cygwin

However, some of these instructions and packages I still need to confirm. Some new packages have been added since I last tried installing them on Cygwin, and I don't know for sure if all of these packages are usable on Cygwin yet (or if I'm not missing a few). I'm not at my Windows machine right now though so I'll have to confirm this later.

src/doc/en/installation/cygwin*.txt should be removed from source tree and gitignored.

tests on #29295 seem to suggest that libcypt0 package should be added to the list.

All of these build errors should be fixed in follow-up tickets.
Needs review!

looks good. It's great that GH actions provide means to test on cygwin.
