### Describe the bug

When uploading a file over 5mb Amplify performs a multi-part upload. When this upload completes there are multiple progress updates sent in a burst with a completion percentage of 100%. The number of such updates appears to be proportional to the size of the file - for a file measuring 472mb, I noted that this resulted in several hundred callbacks.

There should only be one progress update sent with a completion percentage of 100%.

### Reproduction steps (if applicable)

1. Create an app that can upload a file to S3 with Amplify
2. Attempt to upload a file that is >= 5mb. This will result in a multi-part upload.
3. Observe the progress updates received. Note that there are multiple callbacks with progress == 1.0. The larger the file, the higher the number of such callbacks received.

### Code Snippet

```kotlin
Amplify.Storage.uploadFile(
StoragePath.fromString(path),
file,
StorageUploadFileOptions.defaultInstance(),
{ Log.i("MyAmplifyApp", "Fraction completed: ${it.fractionCompleted} (${it.currentBytes} / ${it.totalBytes})") },
{ Log.i("MyAmplifyApp", "Successfully uploaded: ${it.path}") },
{ Log.e("MyAmplifyApp", "Upload failed", it) }
)
```

### Additional information and screenshots

_No response_

Start with the Amplify.Storage.uploadFile entry point and reproduce the issue using a file at least 5 MB, observing fractionCompleted callbacks during multipart upload. Done means a multipart upload emits only one progress update with fractionCompleted at 1.0, while still reporting successful completion.
