CSS perfomance improvements

[selul]

Let's try to do the following to have a better performance for visualizer charts:

• Load front.css and inline style, we don't need a separate CSS file for that since the CSS is minimal. Apply same thing for front.css in PRO.
• Review datatable and chartjs CSS and load that in footer, you can review this on how to do it https://wordpress.stackexchange.com/a/186066

@selul I have added inline CSS instead of loading the front.css file in both plugins.
For the second task datatable and chartjs styles are already loaded in the footer so we can't do anything there.

@girishpanchal30 Tested with Visualizer lite and both lite and pro and didn't find any problem, the enhancement seems to work fine 👍
