Now these variables can be used along with os_type in the enabled_if
field of libraries

I remember reviewing in the train but the approval must not have gone through. Looks good!

This mega PR does the following:

- adds cloud.drone.io CI tests to check that all packages are
  coinstallable.  This will ensure that we can always clone all
  the overrides here into a duniverse and have them build.

- to enforce the above, we remove duplicate packages here,
  unlike the stable opam-repo. This implies that we can't do
  fancy opam solver tricks for versions of things, which is
  steadily being solved by adding smarts to dune to differentiate
  based on build variables (e.g. enabled_if in ocaml/dune#2164)
  See tarides/opam-monorepo#3 for more discussion.

We also add dune ports for:

- ppx_tools: has a small ugly tracked in ocaml/dune#2198.

- ocamlfind: splits up the opam packages into a findlib
  opam package that installs the libraries, and ocamlfind that
  installs the binaries (ocamlfind/ocaml wrapper) to work with
  the toplevel.  This one doesn't have all the bells and whistles
  of the upstream, so we will need to port things like bytecode
  only and non-dynlink arches to the dune configurator.

We remove ports which are now upstream, such as psq and lru

CHANGES:

- Restricted the set of variables available for expansion in the destination
  filename of `install` stanza to simplify implementation and avoid dependency
  cycles. (ocaml/dune#2073, @aalekseyev, @diml)

- [menhir] call menhir from context root build_dir (ocaml/dune#2067, @ejgallego,
  review by @diml, @rgrinberg)

- [coq] Add `coq.pp` stanza to help with pre-processing of grammar
  files (ocaml/dune#2054, @ejgallego, review by @rgrinberg)

- Add a new more generic form for the *promote* mode: `(promote
  (until-clean) (into <dir>))` (ocaml/dune#2068, @diml)

- Allow to promote only a subset of the targets via `(promote (only
  <pred>))`. For instance: `(promote (only *.mli))` (ocaml/dune#2068, @diml)

- Improve the behavior when a strict subset of the targets of a rule is already
  in the source tree for projects using the dune language < 1.10 (ocaml/dune#2068, fixes
  ocaml/dune#2061, @diml)

- With lang dune >= 1.10, rules in standard mode are no longer allowed to
  produce targets that are present in the source tree. This has been a warning
  for long enough (ocaml/dune#2068, @diml)

- Allow %{...} variables in pps flags (ocaml/dune#2076, @mlasson review by @diml and
  @aalekseyev).

- Add a 'cookies' option to ppx_rewriter/deriver flags in library stanzas. This
  allow to specify cookie requests from variables expanded at each invocation of
  the preprocessor. (ocaml/dune#2106, @mlasson @diml)

- Add more opam metadata and use it to generate `.opam` files. In particular, a
  `package` field has been added to specify package specific information.
  (ocaml/dune#2017, ocaml/dune#2091, @avsm, @jonludlam, @rgrinberg)

- Clean up the special support for `findlib.dynload`. Before, Dune would simply
  match on the library name. Now, we only match on the findlib package name when
  the library doesn't come from Dune. Someone writing a library called
  `findlib.dynload` with Dune would have to add `(special_builtin_support
  findlib_dynload)` to trigger the special behavior. (ocaml/dune#2115, @diml)

- Install the `future_syntax` preprocessor as `ocaml-syntax-shims.exe` (ocaml/dune#2125,
  @rgrinberg)

- Hide full command on errors and warnings in development and show them in CI.
  (detected using the `CI` environment variable). Commands for which the
  invocation might be omitted must output an error prefixed with `File `. Add an
  `--always-show-command-line` option to disable this behavior and always show
  the full command. (ocaml/dune#2120, fixes ocaml/dune#1733, @rgrinberg)

- In `dune-workspace` files, add the ability to choose the host context and to
  create duplicates of the default context with different settings. (ocaml/dune#2098,
  @TheLortex, review by @diml, @rgrinberg and @aalekseyev)

- Add support for hg in `dune subst` (ocaml/dune#2135, @diml)

- Don't build documentation for implementations of virtual libraries (ocaml/dune#2141,
  fixes ocaml/dune#2138, @jonludlam)

- Fix generation of the `-pp` flag in .merlin (ocaml/dune#2142, @rgrinberg)

- Make `dune subst` add a `(version ...)` field to the `dune-project`
  file (ocaml/dune#2148, @diml)

- Add the `%{os_type}` variable, which is a short-hand for
  `%{ocaml-config:os_type}` (ocaml/dune#1764, @diml)

- Allow `enabled_if` fields in `library` stanzas, restricted to the
  `%{os_type}`, `%{model}`, `%{architecture}`, `%{system}` variables (ocaml/dune#1764,
  ocaml/dune#2164 @diml, @rgrinberg)

- Fix `chdir` on external and source paths. Dune will also fail gracefully if
  the external or source path does not exist (ocaml/dune#2165, fixes ocaml/dune#2158, @rgrinberg)

- Support the `.cc` extension fro C++ sources (ocaml/dune#2195, fixes ocaml/dune#83, @rgrinberg)

- Run `ocamlformat` relative to the context root. This improves the locations of
  errors. (ocaml/dune#2196, fixes ocaml/dune#1370, @rgrinberg)

- Fix detection of `README`, `LICENSE`, `CHANGE`, and `HISTORY` files. These
  would be undetected whenever the project was nested in another workspace.
  (ocaml/dune#2194, @rgrinberg)

- Fix generation of `.merlin` whenever there's more than one stanza with the
  same ppx preprocessing specification (ocaml/dune#2209 ,fixes ocaml/dune#2206, @rgrinberg)

- Fix generation of `.meriln` in the presence of the `copy_files` stanza and
  preprocessing specifications of other stanazs. (ocaml/dune#2211, fixes ocaml/dune#2206,
  @rgrinberg)

  case of syntax errors. (ocaml/dune#2223, @rgrinberg)

- In .merlin files, don't pass `-dump-ast` to the `future_syntax` preprocessor.
  Merlin doesn't seem to like it when binary AST is generated by a `-pp`
  preprocessor. (ocaml/dune#2236, @aalekseyev)

- `dune install` will verify that all files mentioned in all .install files
  exist before trying to install anything. This prevents partial installation of
  packages (ocaml/dune#2230, @rgrinberg)
