fpga: tools: Add modelsim to make sim targets

This adds a simulation make target that allows you to run ModelSim
natively rather than through Vivado.

Adds or modifies the following simulation make targets:
make vlint    - Brake up compilation to Verilog/SystemVerilog/VHDL
make modelsim - Depends on make vlint and invokes modelsim

Adds the following variables:
MODELSIM_ARGS - Added to invocation of ModelSim
SVLOG_ARGS    - Added to SystemVerilog invocation of vlog
VLOG_ARGS     - Added to Verilog invocation of vlog
VHDL_ARGS     - Added to VHDL invocation of vcom
