feat(model): added throwOnValidationError option for bulkWrite and insertMany

[lpizzinidev]

Summary
Added throwOnValidationError option for Model.bulkWrite and Model.insertMany (default to false).
If set to true and ordered: true the methods will throw an error if there were operations that failed validation, but all operations that passed validation succeeded.

Example

const createdUser = await User.create({ name: 'Test' });

// Will throw an error
await User.bulkWrite(
  [
    {
      updateOne: {
        filter: { _id: createdUser._id },
        update: { $set: { age: 'NaN' } },
        upsert: true,
      },
    },
    {
      updateOne: {
        filter: { _id: createdUser._id },
        update: { $set: { age: 13 } },
        upsert: true,
      },
    },
  ],
  { ordered: false, throwOnValidationError: true }
);

Notes
Let me know what could be a valid error message.
I commented out a test case that was causing the test script to fail.

Closes #13256

LGTM so far, but error class needs to be implemented

[vkarpov15]

A good start, but I think we need a new error class for this. Can you add a MongooseBulkWriteError class that contains response from server, validationErrors list of validation errors, and results array?

Closing in favor of #13410
