[sv-bc] Examples of parameterized class static functions

Here are some trivial examples of using parameterized
classes to mimic parameterized functions. This would
also trivially map to parameterized tasks, types, etc.
The only current LRM issue is 1527 (use as a constant
function).

Gord

class f#(type T = int);
    static function T f (T a); return a; endfunction
endclass

`define dofunc(base,val) base#(type(val))::base(val)

module top;
   int v1 = f#()::f(4);
   typedef f#(reg) freg;
   int v2 = freg::f(1);
   typedef enum {red, blue} Color;
   Color c = blue;
   Color v3 = `dofunc(f,c);

   initial #1 $display(v1, v2, v3);
endmodule
