Fix analytics reporting (new property, new GA APIs)

[mikehardy]

the steps as I see them:

• kill the old analytics property, as there was a period in time where the preferences key was inverted incorrectly - that is analytics are supposed to be very strictly opt-in but they were default opted-in which is incorrect and would be a trust violation. Luckily it only happened after analytics were disabled on the backend so no harm, but we need to kill the old property to make sure no person has data they didn't opt-in shipped off device
• make a new analytics property
  • completed in chore: reset analytics opt-in #15271
• fix up https://github.com/mikehardy/google-analytics-java so it works with the new breaking change / major upgrade to google analytics (or find someone else that has forked and done it, or any other open-source-license-compatible implementation that can talk to google analytics...)
• integrate that here

Additional info from Discord discussion:

AnkiDroid has a problem specifically in that we cannot use their libraries because they are not open-source compatible so we have to use their cloud APIs more directly (previous was REST hits) via an intermediate library which is what the google-analytics-java library under my username on github is

So, the task is to forward-port google-analytics-java to the new google analytics style, or find some other open-source-license-compatible library that implements it already, so we have something open-source-license-compatible, then forward-port AnkiDroid to that.
