[CP][beta channel] Fix crash when developing with DDC

merge instructions: clean merge

What is the issue: DDC had an old undiscovered bug. A certain rare code pattern triggers the issue and in that case the app cannot be loaded for development (the code crashes while loading). The pattern involves an inheritance chain that forms a cycle between classes and type parameters.

Recently a Flutter Web app encountered this pattern and started hitting this issue.

What is the fix: A change in DDC to break the cycle in the generated code.

Why cherrypick: We only know of one affected customer, but the result makes the product unusable in that case.

Risk: low, change is relatively small, we'll get a better signal of risk after the next roll to internal customers tomorrow.

Link to original issue(s): flutter/flutter#64011
