Docs: tidying
- Use `:file:` role for file names, as well as `:makevar:` and `:program:`.
- Remove deprecated `linux-arm` and `linux-riscv64` oss-cad-suite targets.
- Add link to ABC.
- More (and better) links to code examples.  Formatted `:file:` text with link
  to source on github.
- Includes a few extra todos (mostly picking up inline code blocks and a couple
  intro reminders).
- Fixing a few missing `:yoscrypt:` and `:cmd:ref:` tags.
- Reflowing some paragraphs for spacing/width.

Docs: some restructure of advanced section
- Filling out index descriptions for `using_yosys` and `using_yosys/synthesis`.
- To discourage skipping over these index pages, the toctree in
  `using_yosys/index` is hidden and instead has inline links to the two
  subsections.
- Tidying todos.
- Moves technology mapping to `techmap_synth`, leaving the techmap by example in
  the internals section. `yosys_flows` gets split up, with the coarse-grain
  intro replaced by `synthesis/index`, the extract pass moving to
  `synthesis/extract` and model checking to `more_scripting/model_checking`.

Docs: optimization passes
Working on `opt.rst`.
Replace the hardcoded `opt` psuedo code listing with a `literalinclude` from `/cmd/opt.rst`.
Reorder and update `opt_*` list to match current `opt`.
Expand sub-section titles with the function of the pass (keeping the `:cmd:ref:` part at the end to prevent the Esbonio error in vscode when a heading starts with a directive).
Move comments about `clean` and `;;` being aliases into final `opt` subsection.

Also renames `Test suites` -> `Testing Yosys`.

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.

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.

Working on extensions doc
Moved the last files out of the resources directory.
Some tidy up/reformatting of the extensions to allow literalincludes from `my_cmd.cc`.
Most (all?) of the getting started guidelines file is either in the quick guide section, or sections referenced by it.  Instead of including it verbatim, we'll instead just leave a reference to it but then jump straight into the quick guide.
Include an image for the absval generated module.  Still needs more surrounding text but it's good enough for now.

Also includes some other minor tidying, including removing the no longer used abc_01 code example.

TODOs
Blocking tasks are now capital TODO (compared to non-blocking todo).
Updated some of the todos.
Added note about which intel synth does which families.
Rename extended Yosys universe to Yosys family.
Added brief text to landing page, and also a note about the restructure and where to find old docs.
Moved todolist above ToC in preparation for disabling it in the config (so that it doesn't need it's own header).

Fixed pdf build, was previously breaking on trying to include the svg badges.

Updates to install and tests
Includes CAD suite info and details on the OSS CAD suite nightly build targets.
Instructions for building from source, largely based on the readme but with some minor modifications.
Tests are still WIP, but we replaced the old test suites with a brief comment on the github workflow tests.  Still needs more on the tests themselves and how to run them locally.
Also an extra todo on the index page.

Added `load_design.rst` to more scripting.
Split fsm handling and abc out of optimization passes. Also moved things around to match the general flow previously described.
Changed generic `synth` for `prep` instead.

Also updating the counter example to match.

Aims to reduce redundancy, and simplify the getting started section.
Details on things like `proc`, `memory` and `fsm` should instead be in the advanced section (under the new `synth` subsection).

Makefiles now have `clean` target.
Also fixed top level makefile calls to images directory.
More yosys scripts instead of inline yosys commands in makefiles (which also means they can be included in the accompanying document when talking about the image generated).
Fixed another couple image generators that were still outputting pdf directly.
Fixed some hanging image references which hadn't been updated.
Adjusted some text related to images, and included a couple more intermediate images on `memdemo`.

Updating todo text and assorted fixes
Fix #3905 by removing emoji (and move the comment into the if block for less ambiguity).
Adds `latexmk` to README.

Note that latexpdf doesn't seem to like `cmd:ref` links, possibly because the
reference location is inside a latex comment block, but I was under the
impression that there was a reference location in there previously which was
working fine.  May be related to how the `cmd:def` block expands (or doesn't as
the case may be).
