Add extra information to dumpJITMemory
https://bugs.webkit.org/show_bug.cgi?id=197998

Reviewed by Saam Barati.

Source/JavaScriptCore:

Add ktrace events around the memory dump and mach_absolute_time to link the
events with the entries in the dump. Additionally, add a background queue
to flush on a configurable interval, since the atexit callback does not work
in every situation.

* jit/ExecutableAllocator.cpp:
(JSC::dumpJITMemory):
* runtime/Options.h:

Source/WTF:

Add a new trace point code for JSC::dumpJITMemory

* wtf/SystemTracing.h:

Tools:

Add description for the new dumpJITMemory trace point code.
