[AX] Clean up static_cast<> to cast from AccessibilityObject

• Component: Accessibility
• Status: RESOLVED FIXED

[Gyuyoung Kim]

ACCESSIBILITY_OBJECT_TYPE_CASTS can support more helpful casting functions. So, we need to use them as much as possible. This patch cleans up all static_cast<> in accessibility.
This patch generates toAccessibilityFoo() in order to replace static_cast<> with it.

 - Generate toAccessibilityARIAGridRow()
 - Generate toAccessibilityImageMapLink()
 - Generate toAccessibilityListBox()
 - Generate toAccessibilityListBoxOption()
 - Generate toAccessibilityMenuListOption()
 - Generate toAccessibilityMenuListPopup()
 - Generate toAccessibilityScrollbar()
 - Generate toAccessibilitySlider()

I think it's a good cleanup. Setting the r+ now, but please fix those small things pointed out below before landing. Thanks!

You should declare it as virtual and use the FINAL modifier here too if you are declaring this in upper classes as a virtual method (as you are)

FINAL missing
