fix(host-targets): remove unnecessary windows libc waterfall additions

ANYOS already provides ['none', 'gnu'] for gnu hosts and the extended
['none', 'gnu', 'musl', 'libc'] for libc hosts, which reaches static
('none') Windows packages. Explicit msvc preference was also wrong
since msvc requires vcredist — 'none' is always preferred.
