The global packages path could cause tests to fail when it would be overriden to unexpected (in test setup) values. Remove most usage and make it a configuration on buildInfo, along with most other build information. Cleanup the asset builder to require the .packages path and the resident runners to no longer require it, since they already have the information in build_info.

It needs to stick around for the fuchsia deps we do not control.

Filled #60232 for remaining work.

Revert "Revert "[PageTransitionsBuilder] Fix 'ZoomPageTransition' built more than once (#58686)" (#59992)" (#60245)

These tests will hit the real Cache, failing if the flutter root has been modified

First pass at fixing #57985 and implementing #59602

This doesn't have enough metadata to be useful for IDEs yet, but it prevents the issue from getting worse while we iterate on it.

WebAssetServer could fail if some of the global statics it depended on were initialized in a different order. Fix this by removing globals.

Delete dwds startup test that needs to spawn a real server.

Remove the version checking and associated warnings. The Linux template
and build process will now be subject to more typical Flutter breaking
change policy, and should no longer require regularly deleting and
recreating the platform directory.

The vm_service_integration test flake is caused by trying to call the method before the framework is initialized (and the extension added). The run errors failure is caused by the error taking some time to propagate to the harness
