Performance optimization for ActiveRecord#column_defaults
Memoize the #column_defaults class property, as ActiveRecord does
for other properties in this module.
This change addresses slowness in ActiveRecord initialization
introduced starting in Rails 5.0. This method's performance has not
changed with Rails 5, but it is now called much more frequently than
before: every time an STI model is instantiated.
