Bug 1670261 - Re-export the Glean Kotlin bindings from GeckoView. r=agi

This also upgrades to Kotlin 1.3.50, which is required to due Glean
requirements. Fenix is already on 1.4, so that's no problem.

We also turn the geckoview_example into a multiDex application.
Otherwise we run into the 64k dex symbols size limit.
