Support "resolutions" in typescript libraries

[geropl]

Currently only the local package.json is copied into the build directory. Because the workspace global package.json (with it's resolutions fields) is missing package resolution behaves different to outside of leeway.

One way to "fix" this would be to add a config workspaceRootPackageJson and merge that into the local package.json.

Also @AlexTugarev discovered that the installer-package.json which we generate to install Typescript packages does not contain the resolutions from the package it installs. This seems to have the effect that yarn ignores the resolutions (at least in case they do not match the version patterns) which leads to different build results (breaking builds).

If the above is true there are two (closely related) tasks here:

• Merge resolutions from the workspace root package.json into typescript packages
• Copy resolutions from each Typescript package into it's installer-package.json
