debugger: Add a couple more keybindings (#31103)

- Add missing handler for `debugger::Continue` so `f5` works
- Add bindings based on VS Code for `debugger::Restart` and
`debug_panel::ToggleFocus`
- Remove breakpoint-related buttons from the debug panel's top strip,
and surface the bindings for `editor::ToggleBreakpoint` in gutter
tooltip instead

Release Notes:

- Debugger Beta: Added keybindings for `debugger::Continue`,
`debugger::Restart`, and `debug_panel::ToggleFocus`.
- Debugger Beta: Removed breakpoint-related buttons from the top of the
debug panel.
- Compatibility note: on Linux, `ctrl-shift-d` is now bound to
`debug_panel::ToggleFocus` by default, instead of
`editor::DuplicateLineDown`.
