windows: bump minimum to Vista (from XP)

After this patch curl requires targeting Vista or newer, and a toolchain with Vista support. Supported MSVC compilers (VS2010+) all support Vista: - VS2012+ target Win8 (or later) by default. - VS2010 targets Win7 by default. Supported mingw-w64 versions (v3+) all support Vista: - mingw-w64 v9+ target Win10 by default. - mingw-w64 v8 and older target Server 2003 (~XP) by default. After this patch it may be necessary to override the default Windows target version to Vista (or newer) via: autotools: `CPPFLAGS=-D_WIN32_WINNT=0x0600` cmake: `-DCURL_TARGET_WINDOWS_VERSION=0x0600` - mingw-w64 v6+ allow changing the default at toolchain build-time. Notes: - For non-MSVC, non-mingw-w64 toolchains, `if_nametoindex` needs to be allowlisted in `curl_setup.h`, if they do support it. Fixes #17985 (discussion) Closes #18009
