Android: Fix uploading GIF URI (#45826)

Summary:
In Android, when constructing a multipart body for a file and that file source is a uri (base64-encoded) we do the following:
1. Decode the base64 string into bytes
2. Create a bitmap object
3. Compress the bitmap object as PNG into new bytes

The process does an unnecessary work (bytes -> bitmap -> bytes) and creates unexpected results e.g. a GIF file will be converted into PNG when uploaded. This PR removes the unnecessary steps (2 and 3).

## Changelog:

[ANDROID] [FIXED] - Fix uploading GIF URI

Pull Request resolved: https://github.com/facebook/react-native/pull/45826

Test Plan:
1. Upload a GIF; use URI (base64-encoded)
2. Verify that the uploaded file is a GIF

```js
const formData = new FormData();
formData.append('photo', {
  uri: GIFURI,
  type: 'image/gif',
  name: 'photo.gif',
});

fetch(UPLOAD_URL,
{
    body: formData,
    method: "POST",
}):
```
