When `const LocalPlatform` is used immediately and not passed as a
dependency it does not have utility over the static properties from
`dart:io`. Remove these uses to reduce the noise around how the
instantiable `Platform` class is used.

Remove caching of FlutterView and poll forever if the list of flutter views is empty. Added test for missing release mode logic.

This reverts commit 209bdcb6.

Remove caching of FlutterView. Perhaps the FlutterView RPC might return an empty list if the VM is not quite up yet? We had some old logic to poll the flutter views RPC for up to 200ms. That doesn't seem like a great approach, so instead we could forgo it entirely and trust that either the views come up before the developer tries to interact, or we crash.

* Trial PR to use an engine that has the null safety unfork CL in it.
