Log:
Allow LanguageRuntimes to return an error if they fail in the course of dynamic
type discovery
This is not meant to report that a value doesn't have a dynamic type - it is
only meant as a mechanism to propagate actual type discovery issues (e.g.
malformed type metadata for languages that have such a notion)
This information is used by ValueObjectDynamic to set its own m_error, which is
a fairly sharp and heavyweight tool to begin with
For the time being, this is an architectural improvement but a practical no-op
as no existing runtimes are actually setting errors
