Returns an array of an object's own and inherited writable property names.

@param {*} value - input object
@returns {Array} a list of own and inherited writable property names

@example
var defineProperty = require( '@stdlib/utils/define-property' );

var obj = { 'a': 'b' };

defineProperty( obj, 'beep', {
    'configurable': true,
    'enumerable': true,
    'writable': false,
    'value': 'boop'
});

var keys = writablePropertyNamesIn( obj );
// e.g., returns [ 'a', ... ]
