WebCore::HTMLMediaElement::mediaCanStart crashes
https://bugs.webkit.org/show_bug.cgi?id=209950

Reviewed by Jer Noble.

Source/WebCore:

Use WeakHashSet instead of HashSet to record MediaCanStartListeners in Document.

* dom/Document.cpp:
(WebCore::Document::addMediaCanStartListener):
(WebCore::Document::removeMediaCanStartListener):
(WebCore::Document::takeAnyMediaCanStartListener):
* dom/Document.h:
* page/MediaCanStartListener.h:

Source/WebKit:

UserMediaPermissionRequestManager does not need to inherit from
CanMakeWeakPtr<UserMediaPermissionRequestManager> because its
parent class MediaCanStartListener supports WeakPtr now.

* WebProcess/MediaStream/UserMediaPermissionRequestManager.h:
