WebViewAssetLoader: Application private path Raw File access at JavaScript using XMLHttpRequest fails.

**1) Image residing in Application private path.**
lFileUrl =data/user/0/com.company.stub/files/myfolder/IMG-20210826-204423558thumb.jpg

**2)XMLHttpRequest request done from javascript level in cordova based android app.**

var xhr = new XMLHttpRequest();
xhr.open("GET", lFileUrl, true);
xhr.responseType = "blob";
xhr.onload = function(e) {
try {
}

**3)WebResourceResponse shouldInterceptRequest called.**

**### What is expected to happen?**
1)private File access should be pass.
https://developer.android.com/reference/androidx/webkit/WebViewAssetLoader.InternalStoragePathHandler

**### What does actually happen?**

File not found exception seen as WebViewAssetLoader.InternalStoragePathHandler is not handled. Suggest how to handle raw file access.

**Below change works.**
https://github.com/apache/cordova-android/blob/015db819aed3f35892d2b6035781ea4bd752149d/framework/src/org/apache/cordova/engine/SystemWebViewClient.java#L95

```
if(filecaseboolean){ is = new FileInputStream(new File(path));//Imagecase
}else{
is = parentEngine.webView.getContext().getAssets().open("www/" + path, AssetManager.ACCESS_STREAMING);
}
```

**### Version information**

Cordova: Android 10.1.0
device : android 11
app targetsdk : 30 .

**Note:** if `` **everything works fine.**

- [ ✓] I searched for existing GitHub issues
- [ ✓] I updated all Cordova tooling to most recent version
- [✓ ] I included all the necessary information above

Start with framework/src/org/apache/cordova/engine/SystemWebViewClient.java at the linked shouldInterceptRequest and asset-loading locations, then reproduce the XMLHttpRequest for the application-private image on Android 11 with AndroidInsecureFileModeEnabled disabled. Compare the failing www/ lookup with the WebViewAssetLoader.InternalStoragePathHandler behavior. Done means private raw files load through XMLHttpRequest without enabling insecure file mode.
