Shai Berger 72ebe85a26 Fixed #27910 -- Added enumeration helpers for use in Field.choices. 
These classes can serve as a base class for user enums, supporting
translatable human-readable names, or names automatically inferred
from the enum member name.

Additional properties make it easy to access the list of names, values
and display labels.

Thanks to the following for ideas and reviews:

Carlton Gibson, Fran Hrženjak, Ian Foote, Mariusz Felisiak, Shai Berger.
