evaluate the js impact on the default/common theme setup

[ineagu]

Description:

When I install Neve, with all the default settings, we are loading frontend.js, however there is no need for anything like that, if I disable js from browser the site continues to work well.

I think we can have a huge gain if we eliminate js completely for the default settings and load it when really required.

How to reproduce:

1. Install Neve & activate
2. Disable js and check the site

Expected behaviour:

That we are loading the minimum required for the site to work.

Current behaviour:

We are loading stuff like: https://github.com/Codeinwp/neve/blob/787137f4537079c6284e85cbfad0a93b15abcbf6/assets/js/src/frontend/blog.js, which seems to be only for certain, not common cases.

if (window.matchMedia("(max-width: 480px)").matches) { document.write('
