Add data to shouldCollapse method of MR Widget Extension

What does this MR do and why?

This MR adds collapsed Data as a param to the should Collapse method of the MR Widget Extension to enable setting this option dynamically.

This option was so far used in a static way. For certain use-cases (eg. CodeQuality MR Widget) we need this option to be dynamic. The CodeQuality MR Widget will be expandable when there are resolved or new errors, but it won't be expandable if there are no changes.
