AX: Avoid hitting the main thread in [WKAccessibilityWebPageObject
accessibilityParameterizedAttributeNames] in isolated tree mode.

<rdar://problem/108818952>
Reviewed by Tyler Wilcock.
This attribute was being retrieved from the main thread upon request for the
first time and cached. The problem was that this first time occurs during page
load when the main thread is busy rendering the page and building the isolated
tree. This patch avoids hitting the main thread by initializing the cached
array of parameterized attribute names when the WebPage is first set for the
object. Analogously, the initialization of the array of attribute names is now
done on the object init method.
