feature request: be able to bundle preload script

[johnheroy]

For security reasons, require is not defined in the special context in which preload scripts run, but it would be useful for preload scripts to be able to share constants (i.e., method names) between preload scripts and IPC implementations for the APIs exposed in preload scripts.

This feature request is to suggest being able to build the preload scripts with esbuild --bundle option so there is no need for require at runtime.

vite-electron-plugin pursues build performance.
vite-plugin-electron will be bundle Preload-scripts.

Not sure if adding --bundle is worth it :)
