Task Manager: add expand/collapse controls to tab rows, controling visibility of subframe rows

Project Member Reported by nick@chromium.org, Jul 15 2016 
From ben, on a chrome-ui-leads thread: """I'm a bit concerned that adding all the subframes as individual rows default-accessible might make this UI overwhelming. A simple alleviation of this would be to group the subframe rows as child rows of the parent tab & collapse them by default. Perhaps they expand out when sorting by column. See ProcessExplorer on Windows for an example of a tree UI like this."""

What ProcessExplorer does, is it adds +/- buttons to a sortable table layout without making it a treeview layout. In the default layout, child rows are grouped to be after their parents; but sorting (e.g. by memory size) can dislocate that grouping. However, regardless of whether the children currently appear in the order, the +/- button controls whether the a row's children are currently showed in the list.

Implementing this will likely require work both at the views and task manager level.

I think we should keep this idea on file; it solves a problem that users won't encounter until we launch a really process-heavy OOPIF mode, and the right UI choices here may depend on what we actually launch.

You can encounter this problem today in --site-per-process, but we are not on a roadmap to launch full --site-per-process. --isolate-extensions creates less than one subframe process browser-wide, on average. --top-document-isolation will almost never involve more than one subframe process per tab, so the expand/collapse might actually become somewhat annoying if it's only revealing one row.
