[CSSRegions] Wrong auto-height region computation for nested named flows

In the case of an (inner) auto-height region that is absolutely positioned in a named flow that is displayed in an (outer) auto-height region,
when we are doing the layout for the named flow we need to add a "forced region break" also for the case of simplified layout, otherwise
the outer auto-height region will not get the chance to compute its auto-height, ending up with a huge value that was used to initialize
the auto-height computed value before the start of the layout algorithm.

(spatnav) Space&enter should be entered to box instead of simulating click on it.

This fixes the regression after https://codereview.chromium.org/16959002/
which makes it impossible to enter spaces into edit boxes
in spatial navigation mode.

Bug is reproducible only with spatial navigation enabled.
So is this fix.

core: Include wtf files using "wtf/foo.h" form.

Instead of including them as:

\#include <wtf/foo.h>

Change it to include as:

\#include "wtf/foo.h"

Patch generated with thakis's script:

git grep -l '#include <wtf' Source/core/ | xargs sed -i -e 's/#include <\(wtf\/[^>]*\)>/#include "\1"/'

Web Animations CSS: Avoid recursive event dispatch

This was happening under the test runner where a call to
testRunner.notifyDone() was dumping pixels and recursively forcing an
animation update.
