Move common tsconfig configuration to a utility package

[hlxid]

Description

Currently all tsconfig files of all packages extend the tsconfig.common.json that is located in the repository root using relative paths.
Relative paths are error prone and instead we should move the base tsconfig file into a separate package that can be used using the extends field in all other tsconfig files.

Bundles that use nodecg-io could use this configuration package aswell, as some are currently referencing our base tsconfig using relative paths which means they only work if they are located in the correct path.

As a package name I would propose nodecg-io-tsconfig.
