Reviewed by Mario Sanchez Prada.

Source/WebCore:

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. Below toAccessibilityFoo()
are generated.

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

No new tests, no behavior changes.
