Replace typedef with using statement in cdm/core/ files.

[ Merge of http://go/wvgerrit/80805 ]

This change was used only where `typedef` was used for type aliasing,
and not for defining a new type (such as enums, structs, or function
pointer types).

Clang-format was used on the changed files.

Test: WV unit tests
