JS: support internal visibility from friend modules

Friend modules should be provided using the -Xfriend-modules flag
in the same format as -libraries. No manual configuration required for
JPS, Gradle and Maven plugins.

Friend modules could be switched off using the -Xfriend-modules-disabled
flag. Doing that will
  * prevent internal declarations from being exported,
  * values provided by -Xfriend-modules ignored,
  * raise a compilation error on attemps to use internal declarations from other modules

Fixes #KT-15135 and #KT-16568.
