[processing] Show more detail in history dialog

PR Description:

Use a tree display for processing history entries, where the root item for each entry shows the full algorithm log when clicked,
and the python/qgis_process commands are instead shown as child items

This provides more useful information for users browsing the history, while still making the all the previous information available
