Called when a page requests permission to access media.
|requesting_origin| is the URL origin requesting permission.
|requested_permissions| is a combination of values from
cef_media_access_permission_types_t that represent the requested
permissions. Return true (1) and call cef_media_access_callback_t
functions either in this function or at a later time to continue or cancel
the request. Return false (0) to proceed with default handling. With the
Chrome runtime, default handling will display the permission request UI.
With the Alloy runtime, default handling will deny the request. This
function will not be called if the "--enable-media-stream" command-line
switch is used to grant all permissions.
