Add an option to entirely disable sourcemap generation

[ascott18]

I'm having troubles with the generated sourcemaps being wrong. When I try to set a breakpoint in some part of my SFC's <script> block, it is getting mapped to the <style> chunk.

It would be great if we could have the option to just disable the source maps entirely, since I really don't find them necessary anyway. The raw output of the template compiler is perfectly readable and understandable in serve mode since no minification is being performed.

At the moment, I'm doing this as a workaround:

(() => {
var plugin = createVuePlugin();
const oldTransform = plugin.transform;
plugin.transform = async function(code, id, options) {
  var result = await oldTransform?.call(this, code, id, options);
  if (typeof result == "object") delete result.map;
  return result;
}
return plugin;
})()

Disregard - I didn't see the notice about https://github.com/vitejs/vite-plugin-vue2 being created, which doesn't seem to have this problem (and also has such an option).
