Mostly revert "[fuchsia] Prepare for setting the Dart target architecture appropriately in the host binaries."

This reverts commit 9ab39ae09987c16a6d5488162c4d7400dd47e04c.

Keep removal of bad assert in loader.dart.  Keep using script snapshot in cross builds.

We expect to use a checked-in SDK in the Fuschia build instead.

File utils/application_snapshot.gni (right):

https://codereview.chromium.org/2951133002/diff/1/utils/application_snapshot....
utils/application_snapshot.gni:31: extra_inputs = [main_dart]
