This patch adds the ability to run foreground resource tests on `fenix` and `chrome-m` by slightly modifying the existing background resource test. For now the main difference is just sending the app process to the background or leave it in the foreground. Some folders/files are renamed appropriately from `background-resource` to instead `android-resource`. Differential Revision: https://phabricator.services.mozilla.com/D221386
