RFR: 8335642: Hide Transform implementation for Class-File API [v3]

[Chen Liang]

> Removes ClassFile API transformation implementation details accidentally leaked to public API. Users don't have access to classes necessary to correctly implement these transform resolutions. In addition, removed improper `canWriteDirect` and made `ClassFileBuilder::transform` chain returns.
> 
> Replaces #19928.
