[IntelliSense] Allow Multiple Configs in autocomplete

[pm0u]

I would like a setup like the following:

// main-brand.tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    'components/**/*.{js,jsx,ts,tsx}',
    'pages/**/*.{js,jsx,ts,tsx}',
  ],
  theme: {
    colors: {
      red: '#ff0000'
  },
  plugins: [],
}

// specific-styles.tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    'components/specific-components/**/*.{js,jsx,ts,tsx}',
    'pages/specific-pages/**/*.{js,jsx,ts,tsx}',
  ],
  theme: {
    colors: {
      red: '#aa0000'
  },
  plugins: [],
  prefix: 'specific-'
}

To then populate both styles in the intellisense autocompletion when using an editor configuration such as the following:

"tailwindCSS.experimental.configFile": {
  "themes/main-brand.tailwind.config.js": ["pages/**/*", "components/**/*"],
  "themes/specific-styles.tailwind.config.js": ["pages/specific-pages/**/*", "components/specific-components/**/*"]
}

However, it seems like currently there is some sort of logic around "the first matched" config that I only get those styles in the intellisense. It seems that whichever one is first in the object above is the only one provided in intellisense when there is overlap.

This discussion may actually be for the same issue, but it was not clear to me at first: #9328

I have a similar needs, but about prefixes.

We have a monorepo with projects using different prefixes.
