AX: Performance: Certain Web site causes Safari to hang completely while entering form data
https://bugs.webkit.org/show_bug.cgi?id=137420

Reviewed by Mario Sanchez Prada.

If a website has multiple nested tables that are not "accessibility" tables, the performance of accessibility slows to a crawl because:
  1) We are re-computing accessibilityIsIgnored many times.
       As a solution, we can enable the isIgnoredCache when updating children.
  2) When asking if an object isTableCell, we'd go up the parent chain, asking each of those parents the same question, which exploded into calling this many times.
      As a solution, I've changed our determination of isTableCell to instead check if the parent is an accessibiltyTable which should be much faster.

No new functionality. Existing tests cover changes.

[Win] Extend AVFoundationCF Media Implementation
https://bugs.webkit.org/show_bug.cgi?id=137409

Reviewed by Eric Carlson.

This code is not yet being built and tested by our system. Appropriate
tests will be activated when we enable the build.

Most of this patch involves correcting some misuse of the AVFoundationCF API.
1. It is never appropriate in AVCF to pass a null CFErrorRef; instead you must
   pass a CFErrorRef with error type kCFURLErrorUnknown.
2. Because of the asynchronous way we handle the request/response, it is possible
   for AVCF to make two AVCF requests while negotiating the key exchange.

Implement Page::isPlayingAudio().
https://bugs.webkit.org/show_bug.cgi?id=137218

Reviewed by Eric Carlson.

- Add a hasMediaCharacteristics() method to MediaSession. There are three characteristics:
audible, visual, and legible. MediaSession gets the media characteristics information from
its MediaSessionClient.
- Add a mediaStateDidChange() method to MediaSessionClient that MediaSession can call when its
state changes.
- Each Document keeps a set of MediaSessions it contains. When that set changes, or when a MediaSession
changes state, or when its characteristics change, Document::updateIsPlayingAudio() is called. That method
iterates through all its MediaSessions to check if the overall isPlayingAudio state has changed in the Document.
- Each Page caches its overall isPlayingAudio state. Whenever a Document's isPlayingAudio state changes,
it calls Page::updateIsPlayingAudio() which iterates through its frames' documents to calculate its
overall isPlayingAudio state.

No new tests, no behavior change.
