LibWeb: Restore proper functionality of legacy platform objects With the GC heap conversion, the functionality of legacy platform objects was broken. This is because the generated implementation of one of them was used for all of them, removing functionality such as deletion. This re-adds all functionality, where questions such as "does the object support indexed properties?" is instead answered by virtual functions instead of by the IDL generator checking the presence of certain keywords/attributes.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.

AK+Everywhere: Rename String to DeprecatedString We have a new, improved string type coming up in AK (OOM aware, no null state), and while it's going to use UTF-8, the name UTF8String is a mouthful - so let's free up the String name by renaming the existing class. Making the old one have an annoying name will hopefully also help with quick adoption :^)

LibWeb: Implement MediaQuery matching :^) Currently, `evaluate()` recalculates whether the MediaQuery matches or not, and stores it in `m_matches`, which users can query using `matches()`. This allows us to know when the match-state changes, which is required to fire MediaQueryList's change event.

LibJS+Everywhere: Allow Cell::initialize overrides to throw OOM errors Note that as of this commit, there aren't any such throwers, and the call site in Heap::allocate will drop exceptions on the floor. This commit only serves to change the declaration of the overrides, make sure they return an empty value, and to propagate OOM errors frm their base initialize invocations.
