Streamlined filter bar in the Network panel

The filter bar is redesigned to let you filter requests easier and declutter the Network panel.

The corresponding experiment was turned on by default in this version but will be reverted. You can track the progress in crbug.com/1523150.

The new filter bar has two drop-down menus: one for choosing request types and another for hiding data and extension URLs or only showing blocked cookies and requests, and third-party requests. Both menus support multi-select.

To bring back the old filter bar immediately, turn off Settings > Experiments > Redesign of the filter bar in the Network panel.
