build: embed tslib in umd bundles (#1760)

When tslib is listed as part of the globals, it will not be embedded in the UMD bundles.

Users using UMD bundles, shouldn't be needing to add the tslib script, also this is important because tslib is a direct depedency of the package and not a peer depedency.

This is also to align with the Angular FW packages.
