Ruben Fiszel ee4e84d9b4 fix: prevent V8 SIGSEGV by serializing isolate creation and fixing use-after-free
Work around a V8 bug in WasmCodePointerTable::AllocateUninitializedEntry()
that causes SIGSEGV when multiple isolates are created concurrently on
x86_64 Linux (https://github.com/denoland/deno_core/issues/952).

- Add V8_ISOLATE_CREATE_LOCK mutex to serialize JsRuntime::new() calls
- Replace oneshot channel with Arc<Mutex<Option<IsolateHandle>>> shared
  between spawn_blocking and an IsolateDropGuard for proper cancellation
- Remove terminate_execution() call on dead isolate handle in error path
  (was use-after-free: handle dereferenced after JsRuntime already dropped)
- Clear handle before drop(js_runtime) to prevent guard from terminating
  a destroyed isolate
