Per spec, Module::SetSyntheticModuleExport should throw a ReferenceError
when called with an export name that was not supplied when constructing
that SyntheticModule.  Instead, the current implementation crashes with
a failed CHECK().

Add a new Module::SyntheticModuleSetExport that throws (without an ensuing
crash) for this case, and deprecate the old
Module::SetSyntheticModuleExport.
