Also updates the "inserted_into" function as per the previous commit.
Changes the FIXME, as according to the spec there is no notification
system to be notified of things such as the node becoming connected.
Instead, "becomes connected" means when the insertion steps are run,
the element is now connected when it previously wasn't.

This is done in this PR because the insertion steps are run when the
start tag is inserted. This made it try to prepare the script too early
for inline scripts.
The order of operations in the HTML document parser ensures that
the parser document is set before the insertion steps are run.
There's a bit more nuance to how this should really work, but let's at
least make sure we execute <script> elements if you insert them into
the document.
This fills in a bunch of the FIXMEs that was in prepare_script.
execute_script is almost finished, it's just missing the module side.
As an aside, let's not assert when inserting a script element with
innerHTML.
