Subject: [PATCH] test: Add customer_testing script for the flutter/tests
 registry

Adds scripts/customer_testing.dart, invoked by an entry in the flutter/tests
registry (registry/flame.test) so that Flame's tests run as a presubmit
against flutter/flutter framework changes, catching breaking changes early.

flutter analyze runs on every platform over the whole pub workspace, and the
full per-package test suites run on Linux only, since golden and rendering
tests are platform-sensitive.
