Make "value of" lines work with `StreamSubject`.

...by migrating off the deprecated no-arg `check()` overload.

Usages of that method [cause problems for "value of" lines](https://github.com/google/truth/blob/37fd8bea90c0ab4528c4c922c88fa176eb45f65b/core/src/main/java/com/google/common/truth/FailureMetadata.java#L230-L232).

Also, fill in a `typeDescriptionOverride` value for `MultisetSubject`. This is largely a no-op, but it helps under GWT/J2CL (where [we can't infer the type name](https://github.com/google/truth/blob/37fd8bea90c0ab4528c4c922c88fa176eb45f65b/core/src/main/java/com/google/common/truth/super/com/google/common/truth/Platform.java#L72)).

I left `IterableSubject` itself without a `typeDescriptionOverride`, since it has subclasses outside the package, some of which may prefer the more specific names (which are normally automatically derived from the `Subject` class's name—e.g., `AttributeListSubject` would result in `value of: attributeList.size()`). In hindsight, I guess that I could have given _direct_ usages of `IterableSubject` a `typeDescriptionOverride` (by making `StandardSubjectBuilder` pass one), but that seems like more effort than is worthwhile now that I've already tested this CL as it stands.
