Lang Hames d4a4137976 [orc-rt] Add multi-addr dealloc/release to SimpleNativeMemoryMap. (#163025) ...

In an ORC JIT it's common for multiple memory regions to be deallocated
at once, e.g. when a ResourceTracker covering multiple object files is
removed. This commit adds SimpleNativeMemoryMap::deallocateMultiple and
SimpleNativeMemoryMap::releaseMultiple APIs that can be used to reduce
the number of calls (and consequently IPC messages in cross-process
setups) in these cases.

Adding these operations will make it easier to write an
llvm::orc::MemoryMapper class that can use SimpleNativeMemoryMap as a
backend.
