Subject: [PATCH] feat(build): enable importHelpers

BREAKING CHANGE: enable importHelpers on the shared Typescript
configuration file which requires `tslib` to be installed on dependent
packages if the shared Typescript configuration is used.

To migrate, run `npm install tslib` on the dependent package before
updating to this version.

see #4676
