Gerald Squelart 22a7a23613 Bug 1530419 - Move PROFILER_AUTO_THREAD_SLEEP into WinUtils::WaitForMessage from callers - r=mstange
Both `nsAppShell::ProcessNextNativeEvent()` and `MessagePumpForUI::WaitForWork()` have a `PROFILER_AUTO_THREAD_SLEEP` surrounding the `mozilla::widget::WinUtils::WaitForMessage()` call.
However inside `WaitForMessage()` the call to `PeekMessageW()` may trigger a sequence of events (because the system delivers pending messages) that end in the initialization of a new thread, which invokes `ReentrantMonitor::Wait()` where there is a `PROFILER_AUTO_THREAD_SLEEP`.

To avoid this recursion, this patch moves `PROFILER_AUTO_THREAD_SLEEP` from both callers into `WaitForMessage()` to only enclose the actual potentially-sleeping operation `::MsgWaitForMultipleObjectsEx()`.
