[TDR] Remove TODOs linked to issue 445966299.

This is an AI-generated dead TODOs removal. Please review to ensure this
change is correct. This CL was verified by the CL owner before sending
it out. See http://go/dead-todo-removal-agent for more info.

The TODO comment requests a refactoring from
invoke_getStorageKeyForFrame to invoke_getStorageKey. The associated bug
crbug.com/445966299 is 'FIXED', and the fixing CL shows this change was
implemented. The code now uses the new method, so the TODO comment is
obsolete and describes a completed task.
