Reviewed by Chris Fleizach.

Source/WebCore:

Add UserGestureIndicator to increment() and decrement()
so that all accessibility actions are treated as
user actions, not scripted actions.

* accessibility/AccessibilityNodeObject.cpp:
(WebCore::AccessibilityNodeObject::increment):
(WebCore::AccessibilityNodeObject::decrement):

Source/WebKit/chromium:

Add support for press, increment, and decrement actions,
including tests to see whether they're supported on a given
object. This allows Chromium to pass three tests that were
previously skipped.

Tools:

Replace isActionSupported, which takes a platform-specific
argument, with three cross-platform methods.

LayoutTests:

Refactor tests that called isActionSupported to call new
cross-platform variants, and unskip three test for Chromium
as a result.
