Consider modern mingw-w64 UCRT build #68

Building Scipy with Meson, I found I needed to rebuild OpenBLAS with mingw-w64, using the new UCRT linkage.

https://github.com/matthew-brett/openblas-libs/blob/ucrt-build/build_openblas.ps1

In particular, I got the compiler from the rtools, installed with:

choco install rtools

but that is, I believe, equivalent to the latest mingw-w64 UCRT compiler chain.

Would it be reasonable to use that toolchain for the standard CI compile here?

We have moved our windows builds to visual 2017 and are on the cusp of moving to 2019, so as I understand UCRT would be fine.
