We introduced dry-runs to build hooks due to flutter run running concurrently with the inner flutter assemble.

Now we have made the native_assets_builder wait on concurrent invocations, we should be able to do full builds in flutter run which will then be picked up by flutter assemble also invoking the native_assets_builder.

This will simplify the user experience, as there is no longer any reasoning about dry runs or not.
