Various fixes for OE (#418)

Browse Source 
* Add default for getting chunk allocator state

Makes the API same between the two configurations.

* Reduce address space usage for Open Enclave

* Fix OE Pal concept

* Add support for Pal not to provide time.

The lazy return of pages to the OS uses a simple time
based heuristic.  This enables a PAL to not support time,
and return the memory to a central pool immediately.

* Update src/backend/backend.h
