[JITLink][Orc] Add MemoryMapper interface with InProcess implementation

MemoryMapper class takes care of cross-process and in-process address space
reservation, mapping, transferring content and applying protections.

Implementations of this class can support different ways to do this such
as using shared memory, transferring memory contents over EPC or just
mapping memory in the same process (InProcessMemoryMapper).

The original patch landed with commit 6ede65205073d3cf6b1ed4d101e66eae3e0fc8e6
It was reverted temporarily in commit 6a4056ab2ada0046ff97a55a5fb34c2c59504fd1
