Notify inspector of stylesheet changes when removing tree scopes.

Notify inspector of stylesheet changes when removing tree scopes.

We did not update active stylesheet lists when removing a shadow since
there is no collection to update. However, the inspector expects a
notification since it receives a flat vector of active stylesheets from
all scopes.

Add a m_treeScopesRemoved member to not early return from
updateActiveStyleSheets and still call probe::activeStyleSheetsUpdated.
Unless other tree scopes are dirty, calling the inspector is all that
happens.
