Fix build of core_dram_tb and dram_tb and fix tracing

We disabled --trace by default, so we need to stop linking verilated_vcd_c.o
as it doesn't exist in that case.

While at it, make a Makefile variable to enable/disable verilator tracing
and add a couple of generics to those test benches to control tracing
in the L2 and in litedram.

litedram: Add simulation support

This adds a simulated litedram model along with the necessary
Makefile gunk to verilate it and wrap it for use by ghdl.

The core_dram_tb test bench is a variant of core_tb with
LiteDRAM simulated. It's not built by default, an explicit

make core_dram_tb

is necessary as to not require verilator to be installed for
the normal build process (also it's slow'ish).
