bitbake: toaster: ToasterTables add computational fields

This patch adds the ability to pass a function to be computed
for generating a field value in setting up a column in
ToasterTables.

Also adding "displayable" property that can be turned False for
columns that are present in JSON data but are not part of the UI.

Add the "id" column by default for all rows.
