Script: Use &mut JSContext in CheckValidity and ReportValidity Methods (#42820)

This is part of replacing can_gc with the new &JSContext/&mut JSContext
method.
We modify CheckValidity and ReportValidity in various HTML Elements to
use the context instead of CanGc.

Testing: Compilation is the test as this is mostly mechanical.
