These are mostly mechanical changes to replace usage of `testHasValue`
with `testGetValue`.
`testGetValue` will now return `null` instead of throwing an exception
if no data is available.
After the update `TestCoroutineDispatcher`, `TestCoroutineScope` and
`runBlockingTest` are deprecated.
Instead of these new `TestDispatcher`, `TestScope` and `runTest` APIs are used.
Took the oportunity to also replace most of the `runBlocking` calls with the
new `runTest` specially designed for running coroutines in tests API.
To lighten-up our memory usage and startup performance, all of the RecentlyClosed
machinery was converted to use a light-weight TabState - specifically, it's missing
EngineSessionState, which is expensive to obtain during startup, and potentially
very costly to keep in-memory.
When we actually need EngineSessionState (at the point of restoration of a tab), we
read and rehydrate it using provided storage implementation.
This adds a new `recently_closed_tabs` category with then events for all user
interactions on the screen.
The already existent `events.recently_closed_tabs_opened` is still kept for a
bit more time to still have this data available while the new telemetry ride
the trains but can later be removed in favor of this newly added events.
