Spec: https://drafts.csswg.org/css-logical/#directional-keywords

Currently logical values compute to the corresponding physical value,
and the mapping is with respect to the element itself. This patch
makes them compute as specified and changes the mapping to be with
respect to the containing block.

…platform-tests#14097)

The typo in the ref was fixed in
web-platform-tests#13430, but the test
itself was not updated. That's bad.

This patch introduces 2 new prefs:
- devtools.console.stdout.chrome: if true, console API writes on stdout when
                                  used by chrome code
- devtools.console.stdout.content: console API write on stdout when used by
                                   content code.
