wolvic: Enable disk cache

This commit enables disk cache directory for the current user profile.
To verify the correctness one can check that the index files are being
created e.g.:

  $ adb shell run-as com.igalia.wolvic
  find -type f | grep Cache
  ./app_content_shell/content_shell/Cache/Cache_Data/*

This was tested with Oculus Quest 2 (Oculus API) and S21 (No API)
devices.

Worth mentioning that Content Shell, in the upstream, could benefit from
a very similar change in
content/shell/browser/shell_content_browser_client.cc.
