feat(version.py): check_eol() takes cycle, endoflifedate.py bundles Windows

Windows names its endoflife.date cycles after the feature release and the
edition ("11-24h2-e", "10-22h2", "2012-r2", "23h2-ac"), so no prefix of a
version string finds them, and cycle_bounds() reads "11-24h2-e" as
(11, 242, 0) and grades a current build as older than anything listed.

check_eol(cycle=...) takes the cycle name, or a list of candidates from
the most to the least specific. With it, the placement of an unlisted
version above or below the listed cycles and the newer-release comparison
are skipped: named cycles have no order, and Windows reports the same
`latest` build for every edition of a feature release.

update-endoflifedate and the bundled snapshot gain windows.json and
windows-server.json, sorted by product name. Only the two new products
were spliced in; the other products keep their data.
