Summary [JSC] Add option to toggle allocation profiling hooks

rdar://123044980 In https://bugs.webkit.org/show_bug.cgi?id=262827 we introduced some preprocessor hooks allowing for WebKit contributors to decorate different points in the WebKit allocators with profiling code. However, it's a bit of a nuisance for this profiling to only be toggle-able at build time. In order to allow switching allocation profiling extensions on or off more conveniently, let's add a new option to JSC reserved for use in allocation profiling extensions. The main value of this option is that it will communicate its value through the additional bytes of g_config reserved in https://bugs.webkit.org/show_bug.cgi?id=266110, so it may be linked against and queried in the libPAS/bmalloc layer via external reference to g_config, unlike other JSC options which are managed at a later stage and have a C++ interface.
