fix(scss): improve error logs

[bluwy]

Description

There's 3 commits in this PR:

1. Add e.line and e.column to error object when compiler with scss modern api. It's missing by default which makes the file name open-in-editor not have the line/col. (Astro had a test that expected the positional info to exist. I don't think this is a breaking change, but figured nice to fix anyway)
2. (and 3) I fiddled with making the error overlay look better because with no1, modern api error will cause Vite to regenerate a code frame, causing two code frames to appear. At the end, I shimmed e.frame = e.message to prevent it (mimicking same behaviour as legacy api for now)

I think the error messages could be a little better for css preprocessors, but it's a bit subjective so i didn't want to make a too drastic change for now.
