AX: When the page scale changes, FrameGeometry needs to be updated
https://bugs.webkit.org/show_bug.cgi?id=310152
rdar://172792054
Reviewed by Tyler Wilcock.
With ACCESSIBILITY_LOCAL_FRAME enabled, `m_frameGeometry` (stored in in the
AXObjectCache)
is still after page scale changes (zoom, viewport scale, pinch zoom, etc.). We
need to re-
compute the page scale for all frames whenever this changes. By hooking into
`pageScaleFactorDidChange`, we can do this all from the UI process to limit
this to one-way
IPC (UI -> web process), rather than a round trip from the web process.
