Support x86 PerformanceAPI

[PaulDance]

Dear maintainers,

The current version of the -sys crate does not allow for linking against the x86 variant of the underlying PerformanceAPI. It would be useful though, as it is an officially-supported target architecture.

This PR therefore adds it by doing the following:

• Checked that the headers did not need an update: nothing changed since the last one.
• Update the x64 library files.
• Add the x86 library files.
• Add support for linking against these in the build script.
• Check that everything compiles under both i686-pc-windows-msvc and x86_64-pc-windows-msvc.
• Run both the example and the tests compiled for i686-pc-windows-msvc under an x86_64 Windows machine successfully.
• Add partial CI support for the new x86 target. It remains to see if that works.

I am aware that GitHub Actions do not offer means to select any other architecture than x86_64, therefore meaning that this new support would not be fully tested. I included some on a best-effort basis however.

Cheers,
Paul.

thanks, out of curiosity what type of application is it you need i686-pc-windows-msvc for?

in general we don't support that in our crates as don't have any end users using 32-bit Windows as at least for games we've built haven't supported 32-bit for the last 13 years or so

This is for a security product. Sadly, clients often run some really old systems. Supporting them is therefore important to us.

ah that makes sense, will take a look at the PR, doesn't seem it should be too hard to maintain support in for this crate

verified the prebuilt binaries are identical to the ones Superluminal distribute in latest stable version. let's merge this!

Thanks!
