[VLS] add support to CSS container query unit

Feature Request

Support for CSS container queries units such as cqw, cqh, cqi, cqb, cqmin, and cqmax is now available in most major browsers. However, the Vue Language Server (VLS) does not recognize them. Currently, a Vue: expression expected error message is displayed when these units are used.

It would be greatly beneficial if VLS could support these units.
