An ExternalTexture is a texture that is created and owned by gecko, but shared with the webgpu implementation. It is used for webgpu presentation. While this name describes the class well, it is confusing due to webgpu having an entirely unrelated concept of GPUExternalTexture. This patch renames ExternalTexture, and all of its subclasses and uses, to SharedTexture. This still describes the purpose accurately, and has similarities to gl::SharedSurface which serves a similar purpose for our webgl implementation.
