chore: remove std directory (#9361)
This removes the std folder from the tree. Various parts of the tests are pretty tightly dependent on std (47 direct imports and 75 indirect imports, not counting the cli tests that use them as fixtures) so I've added std as a submodule for now.

- * Determines whether an object has a property with the specified name.
- * Avoid calling prototype builtin `hasOwnProperty` for two reasons:
- *
- * 1. `hasOwnProperty` is defined on the object as something else:
- *
- * const options = {
- * ending: 'utf8',
- * hasOwnProperty: 'foo'
- * };
- * options.hasOwnProperty('ending') // throws a TypeError
- *
- * 2. The object doesn't inherit from `Object.prototype`:
- *
- * const options = Object.create(null);
- * options.ending = 'utf8';
- * options.hasOwnProperty('ending'); // throws a TypeError
- *
- * @param obj A Object.
- * @param v A property name.
- * @see https://eslint.org/docs/rules/no-prototype-builtins
