Implement trusted types url setter (#36596)

Browse source 
We now check the sink of script.src for trusted types. This is the first
attribute that we check, other sinks will be implemented in follow-up
changes.

The algorithms currently hardcode various parts. That's because I need
to refactor a couple of algorithms already present in TrustedTypePolicy.
They use callbacks at the moment, which made sense for their initial
use. However, for these new algorithms they don't work. Therefore, I
will align them with the specification by taking in an enum. However,
since that's a bigger refactoring, I left that out of this PR (which is
already quite big).

The other trusted types support (createScript and createHTML) will also
be implemented separately.

Part of #36258
