  Log Message:
  -----------
  AX: Crash caused by multiple concurrent calls to WebKit::WebProcessPool::setMediaAccessibilityPreferences.
https://bugs.webkit.org/show_bug.cgi?id=272480
rdar://125614396

Reviewed by Tyler Wilcock.

The idea of this change is to dispatch the block in setMediaAccessibilityPreferences to a new serial queue instead of to the global queue in order to avoid multiple threads performing the work item concurrently.
