vlog95: Add an error message that SV strings and darrays are not supported 

We can not convert SystemVerilog strings or dynamic arrays to valid vlog95.
This patch adds an error message that they are not supported. There are still
issues with converting some of the dynamic array constructs (the compiler
crashes), but the message is printed before the crash.
