Cannot move to next item in playlist when in a background tab on

Reviewed by Eric Carlson.
In the original implementation of MediaKeySystemPermissionRequestManager in
233845@main prevented
requestMediaKeySystemAccess() from working when the WebPage was in the
background, and a subsequent
change in 236448@main caused the requests to be stored and serviced when the
page went back to the
foreground. However, this left the issue where when a page which was previously
in the background,
and was able to play media requested key system access would have that access
left pending, preventing
users from playing the next item in a playlist.
If a particular port wants to block MediaKeySystemAccess from working when a
page is in the background
it seems the right way to do so would be at the client level, and not within
WebKit. This patch removes
the "canPlayMedia()" check before issuing the key access request.
