[ES6] Drop WeakMap#clear

https://bugs.webkit.org/show_bug.cgi?id=145489

Reviewed by Mark Lam.

ES6 spec intentionally drops the WeakMap#clear
to allow engine to implement WeakMap as a per-object table.

This patch drops WeakMap.prototype.clear.

* runtime/WeakMapPrototype.cpp:
(JSC::WeakMapPrototype::finishCreation): Deleted.
(JSC::protoFuncWeakMapClear): Deleted.
