Like Builder.valueFromString, this function demarshals
a value from a string, but takes a GType instead of gobject.ParamSpec
This function calls Value.init on the value argument, so it
need not be initialised beforehand.
Upon errors FALSE will be returned and error will be assigned a
GError from the GTK_BUILDER_ERROR domain.
