Avoid hardcoding lit-app.js in the webpack config

Currently, the lit-app.js file is the entry point of the application in the webpack config.

const commonConfig = merge([
  {
    entry: './src/lit-app.js',
    output: {
      path: OUTPUT_PATH,
      filename: '[name].[chunkhash:8].js'
    },
   ....

I see several issues with this:

You have to change the config if you want to change the main entry point of your application
If you don't all users of create-lit-app will have an identical lit-app web component in their front-end, possibly leading to conflicts.
I was very confused that my app wouldn't show up any more when I renamed the lit-app element, and it took me a while to figure it out.

I suggest to put the main entry point to be the index.html itself, but any other idea is very welcome!
