feat(build): set hoistTransitiveImports to false in library builds

[Kaciras]

Description

Rollup has an option hoistTransitiveImports to make chunks load as early as possible by adding empty imports to the entry, but it is useless for libraries:

• The library will not be the first-loaded module, which makes hoisting useless.
• Projects may use builders, in which case these extra imports are redundant.

These empty imports have also caused some confusion: rollup/rollup#3332, rollup/rollup#4564

This PR disable hoistTransitiveImports option by default in library build, make the output code more clean.
