VLC 4.0 should build out of the box for Windows ARM. It should build 
like the other Windows targets except adding `-a aarch64` to build.sh. 
It should work with the LLVM Dockers we use (or any llvm-mingw build). 
Not sure there's mingw-w64 for ARM available.

There may be some contribs that don't build properly, for example Qt may 
refuse to build or not understand what's going on. And if it builds it's 
not 100% guaranteed to work. But we have Android and iOS stable builds 
for arm64 that already validate a lot of our code.

I have a machine to test. I just never took the time to work on it.
