Create api docs using jsdoc

[cewert]

This adds automatically generated docs for our code using jsdoc style function comments. Function names, descriptions, params, param types, and return types are automatically grabbed with the option of manually adding more info.

I wasn't able to get search working but I believe that can be fixed after this gets merged and hosted online. At least that was my plan, was to host these docs using github pages.

I put the auto generated docs in the docs/api folder instead of the default docs folder that way we have somewhere to put our other docs like the DEVGUIDE. api might not be the best folder name but I couldn't think of a better name.

Changes

• Install jsdoc and brighterscript-jsdocs-plugin as dev dependencies
• Use theme with dark mode
• Create npm script to generate docs - npm run docs
• Move DEVGUIDE.md to docs/
• Generate docs @ docs/api

This is killer. Looks like search isn't working locally due to CORS policy, so you're right, it'll likely fix itself when hosted.
