Format ts code using Prettier

[DonJayamanne]

Part of #2012

• This PR focuses only on formatting of the typescript code
• A separate PR will (ready to go) be submitted with the necessary CI changes (simple one line change)
• Formatting of Python code and the like can be done as a separate PR
• Files modified:
  • First commit in PR
  • settings.json ensure prettier is used to format code as it is written.
  • tslint and eslint configuration files to ensure prettier respects/uses existing linter settings.
  • package.json new npm packages for prettier
• Other code files
  • Second commit in PR
  • Changes to format (changes done using prettier, not by hand)

(I'd consider #2012 an epic as there are plenty of proposed changes, format python, js, json, css, Ci changes, etc).

Not submitting individual PRs, as I don't see any real benefit as these are changes made by a tool and not by hand. If required I can submit individual PRs for 100 files or so (that would break it into 11 PRs, thats' large).

Summary:

• All code formatted according to pretter
• Code will be formatted automatically in VS Code as you save or manually format.
• Auto fixing linter issues (where possible by the tools) also taken care of as part for formatting
• Separate PR will be submitted for (after this is merged)
  • Contributing guide changes
  • Pipelines changes (to fail CI)

@kimadeline created a new PR as I was having a few problems with the other branch (I had to close rebase and delete the old branch. GitHub lost links, and went looney after that)

I had discussed this change with @DonJayamanne prior. @DonJayamanne thanks for doing this :)
