RFR: 8304871: Use default visibility for static library builds [v2]

[Severin Gehwolf]

> Please review this change for symbol visibility of static library artefacts. This fixes an issue when
> OpenJDK is being used as a base for generating native images preventing the symbols from being
> exported and looked up from the executable. Note that symbol visibity is now controlled by a
> linker version script downstream. This changes nothing for the regularly shipped dynamic libraries.
> 
> Thoughts?
