Consider exposing the screenshot-taking functionality

[p-himik]

Problem Statement

The user feedback dialog is great, but some users (me) might need some extra flexibility that necessitates creating such a dialog manually. However, the screenshot taking code is the most involved part and it would be nice if Sentry API included all the necessary facilities.

Solution Brainstorm

The relevant API passes around preact functionality, so a public version of that API would probably have to pass the Sentry's bundled preact to the internal API. Apart from that, not sure if there's anything else to it.
