Avoid a hang on linux by always create the renderer, even when we have no store_view

[jleibs]

What

• Mitigates: Wayland + Nvidia: rerun --skip-welcome-screen causes Rerun to hang on launch #5283

All this does is re-orders the calls so that we always create a renderer and call begin_frame / before_submit even if the case where we have no StoreView.

In theory this uses a few more resources when skipping the welcome screen, but practically in almost all cases this is only for a few frames until log-data starts arriving.

I want to remove that flag. We should always show the welcome screen imho. I miss it when running pixi run rerun-web

The flag serves a valid purpose when the SDK is spawning a viewer it's about to send data to, to avoid a visual glitch... other than that though we should never use it. I wouldn't have expected it to apply to pixi run rerun-web though.
