feat: Implement Android UI tests for file downloading in Browser

[Tyschenko]

Our current E2E test framework doesn't support interactions inside the WebView. To overcome this issue I wrote native Android UI tests. Currently, there are 3 tests:

1. Download regular file
2. Download base64 file
3. Download blob file

It covers changes from this PR: MetaMask/react-native-webview-mm#51

To run tests you can execute yarn test:native:android
