8384158: GHA: Downgrade Windows GHA runners to windows-2022 temporarily

[gnu-andrew]

This is a backport of the change to use Windows 2022 in spirit rather than like-for-like as 8u does not yet have the GHA restructuring provided by JDK-8287906 (something I would like to address in due course)

While 8u isn't being hit by the change to Windows 2025 in the same way (likely because it uses Cygwin and Visual Studio 2010 & 2017), I think it would be good to keep the operating systems consistent across major releases to avoid potential issues unique to the newer environment that other JDKs are not yet using.

/approval request Backport to sync 8u's Windows OS usage with later JDKs, though the use of Cygwin & explicitly VS20{10,17} seems to be avoiding the issues others have seen with Windows 2025. GHA-only change. Keeps the toolchain versions the same as before GitHub changed the version for windows-2025, so risk is low. The patch was reviewed by Severin Gehwolf.
