Use Server 2022 in CI for mingw jobs

[dpaoliello]

From my previous testing, there is nothing blocking using Server 2022 for the Windows MinGW jobs.

This change:

• Adds new os entries for Server 2022.
• Renamed the Server 2019 os entries (as we'll be removing these over time).
• Moves the mingw jobs to Server 2022 and leaves the msvc jobs on Server 2019.

Partially fixes #92948
