build/lattice/prjtrellis: modify generated verilog instead of creating a wrapper, handle inouts.
...
nextpnr expects TRELLIS_IO on all ios, it's not possible to ensure that with a wrapper.
We now just modify the generated verilog to insert the io constraints and TRELLIS_IOs.

build/lattice/prjtrellis: generate iowrapper to set constraints and TRELLIS_IO
...
PrjTrellis does not yet have constraint files support, constraints are set
with signal attributes and specific TRELLIS_IO instances are requested. This
iowrapper does this work for us automatically.
Remove this code and replace with a constraint file generation code when
PrjTrellis will have constraint file support.

On the iCE40 FPGA, adding buffering allows the SyncFIFO to be placed in
block RAM rather than consuming a large amount of resources.

sim: serial: Send '\r\n' instead of just '\n'

This fixes an issue when running with the HDMI2USB firmware which
expects \r\n to come from the UART. Since the verilator adapter
is just sending \n commands cannot be executed.
Also, one minor whitespace cleanup. (could remove if needed)
