ng generate library adds tsickle 0.36.0 dependency, incompatible to typescript 3.5

[mscudlik]

🐞 Bug report

Description

@angular/cli@8.3.0

ng new creates a project for an app, with a dependency to typescript 3.5
ng generate library adds a dependency to tsickle 0.36.0, which is incompatible to typescript 3.5.

as a consequence library providers cannot use typescript 3.5.
Removing the dependency to tsickle will brake ng build my-lib

So either tsickle should be made compatible to typescript 3.5, or the dependency to tsickle should be removed.

also see angular/tsickle#1048

🔬 Minimal Reproduction

ng new lib-test
cd lib-test
ng generate library my-lib

🔥 Exception or Error

If i remove tsickle manually, ng build will not run anymore:

@mscudlik, if you remove tsickle from your dependencies, you'd need to disable it's usage by setting annotateForClosureCompiler to false in tsconfig of your library.
