Fixes #9777 Add support for resource-id

Track react tag using android.view.View.tag. Allow developers to set resource id by setting component.testID

This pull request fixes the following issue.
#9777

First, you need to declare the resource id by creating /_your_android_studio_folder_/res/values/ids.xml

```
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item type="id" name="my_test_id"/>
</resources>
```

Second, set the testID of your component to a resource name.

```
<Button
onPress={onButtonPress}
title="Press Me"
testID='test_id'
/>
```

Third, run the app and observe the resource id using UIAutomator viewer (/Android/sdk/tools/bin/uiautomatorviewer)

This PR doesn't require a documentation change.
