fix(Android): range requests

[bolivir]

The responseHeaders map is shared between threads, causing simultaneous requests to return the same Content-Length to the browser in case of range requests. See the illustration in ionic-team/cordova-plugin-ionic-webview#453 (the same issue is present Capacitor).

This PR proposes to return a copy of the map on each invocation. Based on #5956
