Fix build on aarch64 Windows

[gaborcsardi]

Need to create the aarch64 windows libs first at https://github.com/r-windows/bundles/releases and then update the winlibs.R file to download from there. Example in curl: https://github.com/jeroen/curl/blob/master/tools/winlibs.R

@jeroen is this something you have time to look at?

[jeroen]

Yes I'll send some PRs this week. It's mostly ready but I am considering to opt-in to the new directX font APIs in cairo and pango while we are at it.

[thomasp85]

Oh, nice. There's a stub for that in systemfonts as well. When I get the time that should be investigated

[jeroen]

Do you case if we enable dwrite support in harfbuzz or not? Or are you not using that functionality from harfbuzz anyway.

Apologies for resurrecting an old issue, but systemfonts still fails to install on windows aarch64:

The headers and libraries are in the aarch64 Rtools, would it be easier to use those instead?
