docs: cleanup docs about shorthands usage & limitations

[layershifter]

This PR cleanups docs about CSS shorthands limitations & deprecates the most of CSS shorthands functions as they are natively supported (see #531 for codemod).

Before

import { shorthands } from '@griffel/react';

const useClasses = makeStyles({
  root: {
    ...shorthands.padding('2px'),
  },
});

After

import { shorthands } from '@griffel/react';

const useClasses = makeStyles({
  root: {
    padding: '2px',
  },
});

Fixes #531.
