Shorten property names in compiled JS output

[nmn]

StyleX generates objects mapping propertyNames to classNames after compilation:

const styles = {
  base: {
    margin: 'khsdgdkj',
    color: 'ksjhgdjf',
    "@media (min-width: 768px)_color": "skjhgfjh", // Legacy deprecated pattern
    "::before_color": "djshgf", // Usage of pseudo elements
    // ...
  }
};

Add a simple transformation step that shorten all property names to a short, but still unique string. This would reduce the size of the JS without any actual changes at runtime:

const styles = {
  base: {
    m: 'khsdgdkj',
    c: 'ksjhgdjf',
    _hash: "skjhgfjh",
    // ...
  }
};
