Vite injects __vitePreload even if the modulePreload option is disabled

[lubomirblazekcz]

Describe the bug

Vite injects __vitePreload on each dynamic import, I would expected this not be included when modulePreload is set to false.

Eg. If I want to handle preloading manually or not at all.

In our scenario, preloading any file causes errors as we have a tricky way of resolving file paths (our code runs inside a vscode controlled iframe).
Specifically __vitePreload injects a stylesheet link that causes our page to not load.

Following the referenced PRs and issues, I understand why it's the case, but is there a workaround to prevent the runtime injection of the preloads today?
