allengleyzer 9e436d1439 Added progress updates for all XMLHttpRequest upload types / fix crash on closed connection
Summary:
This PR includes the same changes made in #16541, for addressing issues #11853/#15724. It adds upload progress updates for uploads with any request body type, and not just form-data.

Additionally, this PR also includes a commit for fixing an `IllegalStateException` when a user's connection gets closed or times out (issues #10423/#11016). Since this exception was occurring within the progress updates logic, it started being thrown more frequently as a result of adding progress updates to all uploads, which was why the original PR was reverted.

To test the upload progress updates, run the following JS to ensure events are now being dispatched:
```
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);

// sending a file (wasn't sending progress)
xhr.setRequestHeader('Content-Type', 'image/jpeg');
xhr.send({ uri: fileUri });

// sending a string (wasn't sending progress)
xhr.setRequestHeader('Content-Type', 'text/plain');
xhr.send("some big string");

// sending form data (was already working)
xhr.setRequestHeader('Content-Type', 'multipart/form-data');
const formData = new FormData(); formData.append('test', 'data');
xhr.send(formData);
```

To test the crash fix:
In the RN Android project, before this change, set a breakpoint at `mRequestBody.writeTo(mBufferedSink);` of `ProgressRequestBody`, and wait a short while for a POST request with a non-null body to time out before resuming the app. Once resumed, if the connection was closed (the `closed` variable will be set to true in `RealBufferedSink`), an `IllegalStateException` will be thrown, which crashes the app. After the changes, an `IOException` will get thrown instead, which is already being properly handled.

As mentioned above, includes the same changes as #16541, with an additional commit.

[ANDROID] [BUGFIX] [XMLHttpRequest] - Added progress updates for all XMLHttpRequest upload types / fix crash on closed connection

Previously, only form-data request bodies emitted upload progress updates. Now, other request body types will also emit updates. Also, Android will no longer crash on certain requests when user has a poor connection.
