winget based setup: don't manually pull meson, use the build's copy

meson is available as an external module/it just needs to be extracted.
That simplifies quite a few things, not to mention a new bug where
specifying it like that would strip the slashes, so if it should be used
manually the mixed style path needs to be used.
