fpga: sim: Add PkgComplex, PkgMath, and PkgRandom

PkgComplex adds functions for doing complex arithmetic in SystemVerilog
simulation.

PkgMath provides mathematical operations and constants that aren't
built into SystemVerilog, such as a constant for pi and the function
round().

PkgRandom adds randomization functions beyond what standard Verilog
supports but that don't require any special licenses or simulators.
