Allow multiline search to be enabled without regex

[miguelsolorio]

Issue Type: Feature Request

Testing #62102

It would be great if when I selected multiline text and triggered Find in Files or cmd+shift+f that Search would know it was multiline and be enabled without having to use regex. This would be a big time saver.

VS Code version: Code - Insiders 1.29.0-insider (97ad72a, 2018-10-31T06:11:22.318Z)
OS version: Darwin x64 18.0.0

I think a great example to use as a reference for developing this feature is this extension in Visual Studio: https://marketplace.visualstudio.com/items?itemName=PeterMacej.MultilineSearchandReplace

You can paste the multi-line text that you wish to search for and it would apply the regex for you.
Also has the ability for multi-line replace.

It's still my go to for multi-line search, however, integrating this functionality into VS Code would be even better.
