Toolkit: Copy config files to dist for plugin use/Fix circleci build errors (#23575)

* replaced run

* consolidated dist and toolkit

* Solved a few more issues
1. Need to explicitly copy circleci config to dist
   so that it's published
2. Detect build directory, and use "local" or "linked"
   mode for local builds.

* Reverted change used only for testing

* grafana-toolkit.js always required now. Copy to dist

* removed grafana-toolkit.dist.js, no longer required

* feedback from code review

* Code review comments 2.
