import.meta.url rewrite doesn't work in web worker

[cedeber]

Describe the bug

The plugin that rewrites import.meta.url uses window.location which is not available in web workers.
If I am right, I think this happens here:

vite/packages/vite/src/node/plugins/assetImportMetaUrl.ts

Line 55 in d66ea0f

)})[${rawUrl}], window.location)`

I believe that using `(window ?? self).location should fix the issue.

Reproduction

Generating WebAssembly with wasm-pack generates a JS file which contains an init() function that contains at the beginning:

if (typeof input === 'undefined') {
    input = new URL('crate_name_bg.wasm', import.meta.url);
}

The workaround is to provide the path directly, like I do here: https://github.com/cedeber/premio/blob/faa64867c913ed183f6941f431d14972e87448e8/app-src/worker.ts

I can confirm this as I stumbled across this myself, but I would suggest to just use location, which is equivalent to window.location in the browser and self.location in the worker. My workaround was to write self.window = {location: self.location} in the web worker code, which feels wrong.
