Some widget get the content id being editing from their config as follow:

config.contentId || config.contentInfo && config.contentInfo.contentId

In grid, the content id is not available in config.
I propose in this PR to add content id to column data.
In widget the content id can be retrieved as follow

config.contentId || config.contentInfo && config.contentInfo.contentId || config.column && config.column.contentId;
