The spec intends to pass through a URL record object as it needs to
be serialized on removal. This has no functional impact on our
implementation other than the double parsing of every URL being
revoked.
It is also missing an error check for an invalid URL being passed
through. This does not impact our implementation currently as we
just end up using an empty URL which is not part of the blob entry
map. This will cause problems once DOMURL::parse is updated to
return an Optional<URL::URL> however.
C++ will jovially select the implicit conversion operator, even if it's
complete bogus, such as for unknown-size types or non-destructible
types. Therefore, all such conversions (which incur a copy) must
(unfortunately) be explicit so that non-copyable types continue to work.
NOTE: We make an exception for trivially copyable types, since they
are, well, trivially copyable.

Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
