Replace TSLint with ESLint and Prettier

[sdirix]

TSLint is officially deprecated. Move to ESLint + Prettier: https://prettier.io/docs/en/integrating-with-linters.html

[lucas-koehler]

• Integrate Prettier in ESLint so that prettier formatting is applied on linting.
• For prettier:
  • use single quotes
  • use line ending auto to be compatible with Windows development using default Git settings.
• Prefer rule recommendations over explicitly configuring many.
• Consider making the packages' configs self-contained in each package as long as there is not too much duplication
