[JSC] Disable ThreadRestrictionVerifier for JIT ExecutableMemoryHandles
​https://bugs.webkit.org/show_bug.cgi?id=69599

Reviewed by Sam Weinig.

DFG JIT manipulates MetaAllocatorHandles across threads, eg in
allocating JITCode buffers on a background thread to execute a
proxy autoconfiguration PAC file but garbage collecting it in
response to allocation on the main thread. Disabling
ThreadRestrictionVerification until there is a verification scheme
that understands this handoff.
