Reland "Reland [clang-repl] Introduce Value to capture expression results"

This reverts commit 094ab478.

Reland with changing `ParseAndExecute` to `Parse` in
`Interpreter::create`. This avoid creating JIT instance everytime even
if we don't really need them.

This should fixes failures like https://lab.llvm.org/buildbot/#/builders/38/builds/11955

The original reverted patch also causes GN bot fails on M1. (https://lab.llvm.org/buildbot/#/builders/38/builds/11955)
However, we can't reproduce it so let's reland it and see what happens.
