Cannot select folder on Google Tv devices.

Is there an existing issue for this?

Description

On Google TV devices, we cannot select a folder with the ROMs. That happens because Google TV devices don't have a system file picker. And when we attempt to select a folder, all we get is a toast saying you do not have an app that can do this.

Other apps, what they do is to use instead a file browser like material files or any other that might be present in the system and use that instead to select a folder.

Retroarch should do the same in order to fix this issue.

Expected behavior

The expected behavior is that some app, like a file system picker or any other browsing app, should pop up, so we can select that folder.

Steps to reproduce the bug

On a Google TV device like NV Shield or Chromecast, try to use any option where you have to select a folder or a file.

Relevant log output

Start by reproducing folder and file selection on a Google TV device such as an NVIDIA Shield or Chromecast, then trace RetroArch's picker flow for platforms without a system file picker. Compare how other installed file-browsing apps can be invoked. Done means selecting a folder or file opens an available picker or browsing app instead of only showing the error toast.
