[CONJS-225] Make result set's meta property non-enumerable - Jira

see https://github.com/mariadb-corporation/mariadb-connector-nodejs/issues/217
Actual implementation return meta as enumerable property of resultset.

example:

const res = await connection.query('select * from animals');

console.log(res):

// [

//    { id: 1, name: 'sea lions' },

//    { id: 2, name: 'bird' },

//    meta: [ ... ]

// ]

A better solution would be to still have meta property, but nonenumerable:

const res = await connection.query('select * from animals');

console.log(res):

// res : [

//    { id: 1, name: 'sea lions' },

//    { id: 2, name: 'bird' }

// ]

const meta = res.meta;

//    meta: [ ... ]
