update mingw-w64 headers to latest git commit

Upstream commit dddccbc3ef50ac52bf00723fd2f68d98140aab80 Martin Storsjö suggested synchronizing with git snapshots rather than waiting for tagged releases. Let's try this for a few releases of Zig and see how we like it. These headers were configured with `--with-default-msvcrt=ucrt`. See related issue #18477.
