Updated errors package to use TypeScript

[binary-koan]

refs https://github.com/TryGhost/Product/issues/4078 (dependency of limit-service)

• Migrated the package to TypeScript
• Removed lodash as a dependency
• Simplified how utils work to just import other files instead of having setup functions and this everywhere
• Isolated utils functions more and marked package as "sideEffects": false so that stdlib doesn't need to be included in frontend bundles
