LibWeb: Remove hacky old ways of running <script> element contents

Browse source 
Now that we're using the new HTML parser, we don't have to do the weird
"run the script when inserted into the document, uhh, or when the text
content of the script element changes" dance.

Instead, we just follow the spec, and scripts run the way they should.
