Update dwds for new DDC type system

[annagrin]

New type system tracking issue: dart-lang/sdk#48585

We use old logic in many places in dwds, for example, for determining the object's runtime kind here:

webdev/dwds/lib/src/debugging/metadata/class.dart

Line 71 in 47287e3

const isFunction = sdkUtils.AbstractFunctionType.is(classObject);

The logic will break with the new types system. Make sure that dwds can handle both cases (and roll internally) before flipping the flag that enables new type system in ddc.

Work tracking:

@nshahan this should be blocking flipping the new type system flag in ddc.
