docs: work on example_synth

Split hardware mapping from `fifo.ys` into `fifo_map.ys`.  Reduces size of `fifo.out` log and allows separate yosys calls in the makefile.

Some tidy up and minor changes in `fifo.ys` for better discussion.
Filled out note on `clean` (changed from `opt_clean`) and introduced `;;`.
Highlighted `$memrd` and added a paragraph about it.
More detail on the flatten and merging of `fifo_reader` block.
Brief discussion on the changes from `$memrd` to `$memrd_v2`.

First pass example_synth done

Split coarse grain representation into 4 parts, loosely: fsm/opt, other optimizations/techmap/memory_dff, DSPs, alumacc/memory -nomap.
Split hardware mapping into subsections as well: memory blocks (map_ram and map_ffram), arithmetic (map_gates), FFs (map_ffs), LUTs (map_luts and briefly abc), and other (map_cells and a note on hilomap and iopadmap).

Also add `-T` flag to Yosys call to remove footer from log output.

Switching example synth to fifo

Fifo code based on SBY quick start.
Instead of showing the full design we are (currently) focusing on a single output (rdata), using `%ci*` to get the subcircuit it relies on.
