readline: add reverse search

Hello Team,

I wanted to add reverse search to repl:

1. Reverse search is supported in linux and unix terminals.
2. User can press ctrl+r to search their history
3. When user types in text, we search through node_repl_history and show off the matching results.
4. When user press enter we run the matching command on our repl.
5. When more results found for a string, pressing ctrl+r again will navigate the search results one by one in a circular fashion (if we reach end of the search result).

It's a work in progress need tests, doc etc.

Initial mode of working is ready.

Need thoughts from community on the idea. But I would love to land this on repl 😍
