4374ca3c - [ORC] Align ExecutorSimpleMemoryManager w/ orc_rt::SimpleNativeMemoryMap (#163693)

[ORC] Align ExecutorSimpleMemoryManager w/ orc_rt::SimpleNativeMemoryMap (#163693) Teach ExecutorSimpleMemoryManager to handle slab reserve/release operations, plus separate initialize/deinitialize for regions within the slab. The release operation automatically deinitializes any regions within each slab that have not already been released. EPCGenericJITLinkMemoryManager is updated to use the reserve (allocate), initialize (finalize), and relesae (deallocate) operations. This brings ExecutorSimpleMemoryManager into alignment with the orc_rt::SimpleNativeMemoryMap class, allowing SimpleNativeMemoryMap to be used as a backend for EPCGenericJITLinkMemoryManager. A future commit will introduce a new MemoryMapper class that will make SimpleNativeMemoryMap usable as a backend for MapperJITLinkMemoryManager. This work will make it easier to re-use in-tree APIs and tools with the new ORC runtime.
