- Add box-sizing:border-box to root container to avoid horizontal scrollbar.
- Control indent size from CSS only, using calc() and a custom property for the indent count.
- Set indent size explicitly to 11px instead of 1em, since our other metrics are in px.
- Remove padding-left from tag lines, so that left padding is a combination of root padding + indents only.

This mostly updates the bindings to the current state.
No actual logic backing them yet.

*Note*: the IDL does *not* need to be checked for matching the upstream spec precisely at this stage. The upstream is evolving, we just need to update in order to start integrating the implementation. What needs to be checked is - how C++ represents the IDL, esp with regards to derived classes, events, and hierarchies.

The trickiest points, arguably, are:
  - WebGPU -> GPU prefix change
  - the goop for interfaces that are not final

Bug 1583252 - Shutdown content process DebuggerServer only once the last connection closes. r=jdescottes

When multiple DebuggerClients starts debugging the same content process target,
the first one to close will destroy the other one as we destroy the server
and the loader as soon as we receive the debug:content-process-destroy message.
We should destroy them only once the last client closes.
i.e. when the last connection registered in the content process is destroyed.

When debugging firefox instance, we open about:devtools toolboxes,
without any remoteId attribute. So that we create a brand new DebuggerClient
instance. For now, this instance is only ever closed if the debugged target
is a local tab. We should try to close the clients for all cases.
Remote debugging clients are ignored and I think are still left opened.

In order to get the browser_page_frameNavigated.js and
browser_page_frameNavigated_iframe.js tests passing under Fission
we can load the test resources from the same site origin as the
initial test document.  This avoids a content browser remoteness
change, which strictly speaking is not what the tests are testing.
