yosys_nextpnr_toolchain: add flow3 option to abc9 mode
...
Add "flow3" option to abc9 mode. This runs FPGA mapping several times,
producing a generally better mapping at the cost of increased runtime
(see https://github.com/Ravenslofty/yosys-cookbook/blob/master/ecp5.md ).
Also, add a "--yosys-flow3" build option to both "trellis" and "oxide".

interconnect/wishbone: Allow passing address_width (In byte addressing).

This is useful to abstract interfaces and propagate address_width.
Idealy, Wishbone should be fully switch to byte addressing since word addressing
has been a source of common issues/errors in the past but compatibility issues
would need to be evaluated first.
