HASPmota meta attribute and improved berry_run

[s-hadinger]

Description:

HASPmota changes:

• added meta attribute with free-form data that can be accessed from Berry
• berry_run is evaluated when the object is fully formed. It can take the current object as an argument but requires a special form like "berry_run":"return def (x) print(x) end"

Related issue (if applicable): fixes #18676
