Update to the clear history dialog
Description:	There is a new UI for the clear history dialog, with new clearing options, and functionality. Users can now see how much data they are clearing for cookies and cache based on the time range they select to clear. Additionally, the dialog has been unified through all entry points for clearing history (hamburger menu, about:preferences#privacy --> clear data, clear history, clear on shutdown). The clear site data dialog will have it's own clear options remembering, separate from clear history and clear on shutdown. The new dialog will be enabled by default.
