Ivan Starkov 333f167c48 feat: Add helper functions for Tailwind support: shorthand expansion and variable substitution (#2371)
## Description

Gonna merge this before next step.

Helper functions to parse tailwind.

1. `expandTailwindShorthand` - Expands shorthand CSS properties into
their long-form equivalents. _'mx' is expanded to 'mr' (margin-right)
and 'ml' (margin-left)._
2. `substituteVariables` - Resolves CSS variables by replacing their
references with actual values. _Transforms `.class { --property: 1px;
margin: var(--property); }` into `.class { margin: 1px; }`._

## Steps for reproduction

See tests.

## Code Review

- [ ] hi @kof, I need you to do
  - conceptual review (architecture, feature-correctness)
  - detailed review (read every line)
  - test it on preview

## Before requesting a review

- [ ] made a self-review
- [ ] added inline comments where things may be not obvious (the "why",
not "what")

## Before merging

- [ ] tested locally and on preview environment (preview dev login:
5de6)
- [ ] updated [test
cases](https://github.com/webstudio-is/webstudio/blob/main/apps/builder/docs/test-cases.md)
document
- [ ] added tests
- [ ] if any new env variables are added, added them to `.env.example`
and the `builder/env-check.js` if mandatory

CSS Engine

This package is designed to render effectively CSS in the format produced by Webstudio Builder. It is using CSS variables for all dynamic parts and can render at runtime as for usage on Live Canvas in the Builder as well as for extracting a fully static style sheet for production.
