More comprehensive workaround for type load deadlocks and domain/assembly unload races.

 * Force all type load events to be queued for the main thread
 * Go back to handling all VM suspend/resume state changes on the client side
 * Return "this has been unloaded" error on type or assembly lookup failure
 * Send domain unload events as soon as possible, before destroying domain metadata
Queue pending type loads for the main thread.
