Added progress updates for all XMLHttpRequest upload types

Summary:
Previously, only form-data request bodies emitted upload progress updates. Now,
other request body types will also emit updates.

Addresses issues:
https://github.com/facebook/react-native/issues/15724
https://github.com/facebook/react-native/issues/11853

This is a bug fix for functionality that's missing on Android. These events are already working correctly on iOS.

Run the following code on Android, and ensure that events are being sent:
```
const fileUri = 'file:///my_file.dat';
const url = 'http://my_post_url.com/';
const xhr = new XMLHttpRequest();

xhr.upload.onprogress = (event) => {
    console.log('progress: ' + event.loaded + ' / ' + event.total);
}

xhr.onreadystatechange = () => {if (xhr.readyState === 4) console.log('done');}

console.log('start');

xhr.open('POST', url);

xhr.send({ uri: fileUri }); // sending a file (wasn't sending progress)
xhr.send("some big string"); // sending a string (wasn't sending progress)

const formData = new FormData(); formData.set('test', 'data');
xhr.send(formData); // sending form data (was already working)
```
