PPAPI: Never re-enter JavaScript for PostMessage.
Blocking renderer->plugin messages can be interrupted by any message
from the plugin->renderer (even async ones). So while handline a blocking
message, such as HandleInputEvent or HandleBlockingMessage, it's currently
possible to re-enter JavaScript. This patch makes that impossible by
queueing up Plugin->Renderer messages sent via PPB_Messaging::PostMessage
while any renderer->plugin sync message is on the stack.
BUG=384528
