Only signed integers are permited in Dynamic Language Binding enumerations [21201]

[richiware]

Description

TypeObject doesn't allow to contain the information whether a enumeration is signed or unsigned. It only stores the bit_bound. To avoid conflicts we were restricting the creation of enumerations using Dynamic Language Binding to only signed integers.
