treewide: re-enable hardware renderer for tauri apps

https://github.com/tauri-apps/tauri/issues/9394#issuecomment-3795449374
suggested that disabling explicit sync on NVIDIA GPUs can solve
Tauri issues with less or no performance cost.
This was applied in 79cfdf. Therefore, this commit reverts the
workaround for NVIDIA GPUs in the affected apps, which should improve
performance on those platforms.
