Bug 1839168 - [devtools] Add InspectorUtils.getAllStyleSheetCSSStyleRules method. r=emilio.

Browse Source 
This method returns a flat list of all the rules in a given stylesheet.
This will be helpful for DevTools so we don't have to recursively walk through
all the children rules (which is slow on the JS DevTools server).
