Recursively include unnamed inner classes in "layout heuristic"

This covers both cases where the inner class is defined in the declaration of a
non-static data member, as needed by clang-cl for

> bridges/source/cpp_uno/msvc_win32_x86-64/except.cxx(799,19): error: unused class member [loplugin:unusedmember]
>             PVOID pExceptionObject;
>             ~~~~~~^~~~~~~~~~~~~~~~
> bridges/source/cpp_uno/msvc_win32_x86-64/except.cxx(801,19): error: unused class member [loplugin:unusedmember]
>             PVOID pThrowImageBase;
>             ~~~~~~^~~~~~~~~~~~~~~

as well as anonymous structs (even if there appears to be no need for that
across the LO code base; they are part of C11 and a widely supported C++
extension).

The newly added TODO will eventually need fixing, but I didn't find a way in
Clang to tell whether a RecordDecl is defined as part of a FieldDecl, and the
issue appears to be of no practical relevance for the current LO code base.
