[Identity] Creates a Identity specific FileProvider

[ccen-stripe]

Summary

Using the default androidx.core.content.FileProvider would cause an collision while trying to merge with client app's AndroidManifest if the client app also has a FileProvider. Creating a custom subclass would solve this issue.

See details in https://commonsware.com/blog/2017/06/27/fileprovider-libraries.html

Motivation

Fix FileProvider collision crash

Testing

• Added tests
• Modified tests
• Manually verified
