Switch to GeckoView 69 Beta.

[pocmo]

This is currently being discussed. Please only merge if there's a decision to ship with GV 69 Beta. ✅

Engineering-wise with GeckoView 69/Beta we no longer need to maintain a copy of the GeckoView version in Fenix and so I deleted Gecko.kt. Just including browser-engine-gecko-beta is enough and the matching GeckoView version will come automatically as transitive dependency.

Heads up that this will break raptor tasks, since this affects our gradle function for returning the current geckoview release.

See reference-browser's printGeckoviewVersion function. If you update fenix's build.gradle to have the same function body, raptor should still work. This can be tested locally with ./gradlew printGeckoviewVersions.
Let me know if you'd like assistance, or if you'd like me to update it and provide you a patch/update your branch

@mitchhentges Thanks! I'll fix that and flag you for review.

@mozilla-mobile/fenix This PR is ready to get in - all stakeholders seem to agree that we want to go with GV 69 as soon as possible.

@mitchhentges I updated printGeckoviewVersion (also without s now). I had to add a check for the selected property since it didn't seem to exist for unresolved dependencies. I couldn't find any code in Fenix yet that actually calles printGeckoviewVersion/s - is that right?

@pocmo thanks!

IIRC by fetching resolutionResult, you trigger the resolution of the entire resolution graph. Is it possible for there to be unresolved dependencies at that point?

... wait a second 🤦‍♂️ we always use the latest raptor these days! Since we aren't matching the raptor version with the geckoview version, you can safely remove printGeckoviewVersion. Sorry!

I'm not sure. 🤷‍♂ It ended up calling selected on some Unresolved.... class that didn't have this property. 🤔

Ah, great. Will do that!
