Refactor optional _getChangeURLAndFetch arguments to objects

The _getChangeURLAndFetch method took many optional arguments, making
call sites difficult to read and making the method difficult to make
changes to.

Refactor the optional arguments into an object with optional properties.
The new Defs.ChangeFetchRequest ensures that the objects are well-typed
and call sites are updated as well as tests.

Feature: Issue 8324
