checkAuthForCreateOrModifyView calls aggregation_request_helper::parseFromBSON without a serialization context, which can cause us failure in passing the serialization flags from the original request to the aggregation request.  checkAuthForCreateOrModifyView is accessed via a regular db command and as a sharded command, the latter of which is out of scope.

checkAuthForCreateOrModifyView
    checkAuthForCreate
        CmdCreate::Invocation::doCheckAuthorization
        CreateCmd::Invocation::doCheckAuthorization    <-- sharded
    checkAuthForCollMod
        ShardsvrCollModCommand::checkAuthForOperation  <-- sharded
        CollectionModCmd::checkAuthForOperation        <-- sharded

Where we have access to the original request, we should use the serialization context from that.  Otherwise, we can pass in a default serialization context for sharded calls.
