Windows css resolution

[Nvos]

Describe the bug

It seems that vite plugin function getAbsoluteId always receives unix path (even on windows) and uses path.sep due to which comparison fails on windows resulting in failing to find matching css in cssCache

Issue seems to be there:

vanilla-extract/packages/vite-plugin/src/index.ts

Line 51 in cff97a7

filePath.split(path.sep)[1] === config.root.split(path.sep)[1])
