Add support for Manifest V3

Manifest V3 (MV3) is a new version of the manifest.json file, which also
comes with several API changes:
https://developer.chrome.com/docs/extensions/mv3/intro/

Therefore, this change does the following:

- Add a new target to the Makefile and release.bash scripts called
  "chromium-mv3-beta"/"CHROMIUM_MV3" which target Chromium using
  Manifest V3.
- Adapt the manifest.gjson template so it is compatible with Manifest
  V3 when the target is "CHROMIUM_MV3".
- Adapt the source code (change the background page to a service
  worker and change chrome.browserAction.* to chrome.action.*).

Also, the following change has been done:

- The "gecko-beta" target in the Makefile has been removed because in
  the end we never released beta versions for Firefox, due to the small
  user base there.
