Add pointer write functionality to MemoryAccess that is needed for implementing redirection manager. It also refactors the code a bit by introducing InProcessMemoryAccess class.

This type has been moved up into the llvm::orc::shared namespace.
This type was originally put in the detail:: namespace on the assumption that
few (if any) LLVM source files would need to use it. In practice it has been
needed in many places, and will continue to be needed until/unless
OrcTargetProcess is fully merged into the ORC runtime.
This re-applies e32b1eee6aab52e2b7b75ee15e506b3e7dd30e68, which was reverted in
20675d8f7dab293172266fdde426c2173b5b3997 due to broken unit tests. This patch
includes fixes for the tests.
Another follow-up to 2815ed57e3c and 19b4e3cfc6a. For unit tests that don't use
an ExecutionSession we need to call ExecutorProcessControl::disconnect directly
to wait for the dispatcher to shut down.

Removing the 'ess' suffix improves the ergonomics without sacrificing clarity.
Since this class is likely to be used more frequently in the future it's worth
some short term pain to fix this now.
All ExecutorProcessControl subclasses must provide an
ExecutorProcessControl::MemoryAccess object that can be used to access executor
memory from the JIT process. The EPCGenericMemoryAccess class provides an
off-the-shelf MemoryAccess implementation for JITs that do not need (or cannot
provide) a specialized MemoryAccess implementation. This simplifies the process
of creating new ExecutorProcessControl implementations.
