[JSC] Drop ThreadSpecificAssemblerData heap buffer under memory pressure
https://bugs.webkit.org/show_bug.cgi?id=313213
Reviewed by Justin Michaud.
Implement AutomaticThread::requestTemporaryStop, so that code can ask
that the underlying thread stops in a restartable way. Add a similar
method to the JIT/Wasm worklists and call it in VM::deleteAllCode.
The destruction of the thread should enough to clear any thread-local
data on all platforms (tested for in
TestWebKitAPI/Tests/WTF/AutomaticThread.cpp).
