* Upgrade Windows builder to `windows-2025`

This is an attempt to address bytecodealliance#10289 and unblock the upgrade of Wasmtime
in the wasmtime-go bindings. Honestly I'm lost in the number of MinGW
bugs we're dodging at this point. Regardless though this is something
that will need to be done at some point anyway and theoretically
shouldn't cause any other regressions, so I figured I might as well go
ahead and do this and hopefully fix some MinGW issues while I'm at it.

* Try a new way of getting windows cpu information

prtest:full
