[ruby] Introduce ApiModelBase (#22052)

The Ruby code that is generated copies numerous methods into every
model. This creates bloat both in file size and run-time memory usage.
This commit introduces a base class for all models to store common
methods. This commit's focus is only on static methods that do not
change between models.
