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`.

synth_ice40 -top fifo -run map_ram:map_ffram
example_synth: hardware mapping Filling out the hardware mapping sections, and actually highlighting the changes in schematics instead of just the memory block. Also includes Part 4 of the coarse-grain rep, looking at `memory_collect` and putting the `synth_ice40 -top fifo -run :map_ram` command in its own (sub)section. Includes a `no_rw_check` section label in `memory.rst` for reference (because I can't remember how to reference by heading). Not sure about the opt output after map_ram section which has an open TODO, and the final steps section is also still open.
