Adds IpdlQueue capability to PWebGL actors. The WebGLChild, used in content processes, implements SyncProducerActor and AsyncConsumerActor because it sends (sync and async) messages and receives responses to them that it reads as async messages. The WebGLParent, used in the compositor process, is a SyncConsumerActor and AsyncProducerActor for dual reasons. Differential Revision: https://phabricator.services.mozilla.com/D68264
