[prim_generic] Prepare to make 2p RAM loadable

The 2p RAM primitive isn't loadable through Verilator at the moment.
This functionality could be added easily for consistency with other
memories (ROM/1p RAM), but enabling that requires first a way to load
memories through DPI without having the width in the DPI-exported
function signature.
