Upgrade lightningcss, disable grid scoping (#8176)

### Description

Implements
https://github.com/parcel-bundler/lightningcss/pull/739/files.

Grid scoping in CSS Modules is disabled because Webpack CSS Modules
handling doesn't handle grid currently. This ensures moving from Webpack
to Turbopack doesn't have mismatching behavior around CSS grid.
