alternative of refactor(rsc): add transformModuleExportWrap and deprecate transformWrapExport #1370

This is an alternative direction of #1380 where we can actually drop "hoist" strategy.

And this actually suggests we shouldn't bother introducing transformModuleExportWrap but just fix transformWrapExport with new take of code???
