[foreign-jextract] [Rev 01] RFR: CSupport::getSystemLinker should not be called from internal API points

[Maurizio Cimadamore]

> Some jextract internal classes call the external getSystemLinker method, which then does a check on the
> `foreign.restricted` property (which is disabled when jextract runs). Trusted internal API points should use the
> internal factory for the system linker instead.
