Add default values to the various options objects in the documentation.

[bponomarenko]

Feature description

When Vue component properties are described in documentation, they are mentioned together with the default values for any optional property. However there are number of aggregated options properties, that are missing default value definitions. It would be helpful to have the default values described in the docs too.

Problem/motivation

For example, it is helpful to know default values for the Core Chart component properties. However Core Chart options property or Axis options documentation doesn't have such information.
