docs: Gets an intrinsic type based on a fully-qualified name.  This could either be the name of an entity,
  like "entity.User", the name of a typekey, like "typekey.SystemPermission", or a class name, like
  "java.lang.String".  Names can have [] appended to them to create arrays, and multi-dimensional arrays
  are supported.
  
  @param fullyQualifiedName the fully qualified name of the type
  @return the corresponding IType
  @throws RuntimeException if the specified name doesn't correspond to any type
