In wgpu, command encoders and command buffers actually share the same identity and resource, so dropping one drops the other. This commit makes it so that our gecko wrappers take that into account. The lifetime is now tied to the encoder which may be held alive by a command buffer if there is one. Differential Revision: https://phabricator.services.mozilla.com/D193313
