Add type-autocomplete for custom utilities

[zslabs]

Description

When adding utilities to override certain properties:

backgroundColor: {
  className: 'bg-c',
  values: { 'palettes.gray.20': '#f0f0f0' },
  transform(value) {
    return { backgroundColor: value }
  },
}

And using them in a style:

className={css({
  backgroundColor: 'palette.gray.20'
})}

The value does resolve correctly and render fine on the frontend, but is not part of the typescript autocomplete in VS Code. The only thing that shows up via autocomplete are values stored for the generic colors token, but what I'm attempting to do is set only certain values to be valid for various properties (text-related colors for color, background properties for fill, background-color, etc).

I'm unsure if this is part of the VS Code plugin or Panda CSS in general though 😕

Problem Statement/Justification

This would expand coverage for custom values.

Proposed Solution or API

Update types for properties to take custom utilities into account.

I just checked this and it seems to work in Panda itself. This must be a vscode plugin bug then.
