LibWeb: Implement performance.now() This patch introduces the HighResolutionTime namespace which is home to the Performance object (exposed via window.performance) performance.now() is currently the only function, and it returns the number of milliseconds since the window object was constructed. :^)

AK: Really disallow making OwnPtrs from refcounted types This looks at three things: - if the type has a typedef `AllowOwnPtr', respect that - if not, disallow construction if both of `ref()' and `unref()' are present. Note that in the second case, if a type only defines `ref()' or only defines `unref()', an OwnPtr can be created, as a RefPtr of that type would be ill-formed. Also marks a `Performance' to explicitly allow OwnPtrs.

LibWeb: Stub out the PerformanceTiming object from Navigation Timing Just have all the timing functions return 0 for now. We can now run the Shynet JS on https://linus.dev/ although the XHR is rejected by our same-origin policy.

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.

LibWeb: Implement performance.timeOrigin This is the origin timestamp of the same monotonic clock used for the performance.now() timestamp. I got a little confused while implementing this, since the numbers are very low. That's because it uses the CLOCK_MONOTONIC system clock, which we start counting from 0 at boot. :^)
