Part of the fixes for #1699.

We currently can't require a module with sideEffects: false. This PR adds a $require$NAME entry to cacheData.imports so we can treat require like it is a wildcard import.

}

asset.cacheData.imports['$require$' + source] = [source, '*'];

This could potentially conflict with a real import, right? e.g. import $require$foo from './foo'

hmm, in imports we would use $id$import$$require$foo as key :

asset.cacheData.imports = {
  "$require$foo": ['foo', '*'],
  "$id$import$$require$foo": ['./foo', 'default']
}

or is there another place where it would conflict?
