LibWeb: Implement whether scripting is disabled based on a realm

Browse source 
Instead of a settings object. This matches updates to the HTML spec as
part of the shadow realm proposal, and begins the refactor of running
scripts on a realm instead of a settings environment object.

Some of the spec steps are slightly messy here (such as in
MainThreadVM.cpp) as this partially implements the ShadowRealm changes
but not other pieces which we have not implemented yet, such as
preparing to run a script also being based on a realm instead of an
environment. But this will be addressed in further commits.
