fix: several regressions in TS compiler (#6177)

This commit fixes several regressions in TS compiler:

* double compilation of same module during same process run

* compilation of JavaScript entry point with non-JS imports

* unexpected skip of emit during compilation

Additional checks were added to ensure "allowJs" setting is 
used in TS compiler if JavaScript has non-JS dependencies.
