AX: Do less work under m_changeLogLock in AXIsolatedTree::clear and AXIsolatedTree::setFocusedNodeID
https://bugs.webkit.org/show_bug.cgi?id=235624

Reviewed by Chris Fleizach.

AXIsolatedTree::clear and AXIsolatedTree::setFocusedNodeID
do work while holding m_changeLogLock that does not require this lock. This
patch moves this work before the lock acquisition so we hold the lock for as short
a time as possible.

* accessibility/isolatedtree/AXIsolatedTree.cpp:
(WebCore::AXIsolatedTree::clear):
(WebCore::AXIsolatedTree::setFocusedNodeID):
Move work that doesn't require m_changeLogLock before we acquire the lock.
