Add feature flag to let the application prints logs to logcat in release builds.

[jmartinesp]

Content

Logs in logcat are enabled now by default in debug and nightly builds based on a new feature flag that can be toggled in the developer options screen, so they can be temporarily enabled in release builds if necessary, while they're disabled by default on those.

Motivation and context

Fixes #4011.

I do not agree with this change, and I have commented the issue here #4011 (comment)

[jmartinesp]

The new changes should be more aligned with what we agreed on, I've updated the description of the PR too.
