Devtools UI: Fix Chrome focus shortcut and add pause debugger shortcut

This change reverts adding Cmd+L clear console shortcut, as it conflicts
with Chrome's omnibox focus shortcut on Mac.

This change also allows the pause script shortcuts to be used while
inside the inspected page, allowing the user to perform a series of
mouse/focus actions before pausing script.
