fix: don't handle file ids that begin with a null byte

[jcarrus]

Description

Rollup has a convention of prefixing some paths with a null byte (\0). Most plugins should just ignore files prefixed with the null byte, and this PR adds the proper handling to the electron-vite asset plugin.

Additional context

This bug is seen in issues like #524 where there's an error:

[vite:node-asset] Could not load C:/Users/krystian/Desktop/test/main/node_modules/test-module/build/package/module.node?commonjs-proxy (imported by main/node_modules/test-module/index.js): The argument 'path' must be a string or Uint8Array without null bytes.

As noted in Rollups "conventions" page:

If your plugin uses 'virtual modules' (e.g. for helper functions), prefix the module ID with \0. This prevents other plugins from trying to process it.

https://rollupjs.org/plugin-development/#conventions

In this case, the electron-vite plugin is not using virtual modules, but if other plugins are using it, electron-vite should not try to process the file.

Similar handling is done in vite's built-in asset plugin:
