1.1.0

CHANGES:

New Features:

• Desktop testing for macOS/Intel (or macOS/ARM64 with Rosetta emulator) and Linux 32/64-bit on Intel/AMD
• Help messages for desktop testing on Windows
• Optional secondary switch two in addition to primary switch dkml enabled with
  input variable SECONDARY_SWITCH=true

Breaking changes:

• The GitLab job names build_linux, build_macos and build_win32 are now private job names .linux:setup-dkml,
  .macos:setup-dkml and .win32:setup-dkml. This means in your own .gitlab-ci.yml you will need an "extends" statement,
  like so:

  build_linux:
    extends: .linux:setup-dkml # ADD THIS ONE LINE!
    script:
      - opamrun exec -- echo Build me some Linux stuff

  Why break the API?

  This change was done so you could do incremental staged builds where job A does only the setup (which caches the OCaml
  compiler) and where the second job B does both the setup and the full build of your OCaml code. By using a private job
  name that starts with a dot (.) like .linux:setup-dkml, both job A and job B can extend from .**OS**:setup-dkml to
  share the setting up of the OCaml compiler cache.

  The benefit you get for the extra complexity is that you are more likely to stay under GitLab runner
  time limits; the shared SaaS GitLab runners time out jobs at 2 hours.
  For example Job A can take one hour or more for Windows when you enable SECONDARY_SWITCH=true.

  Hypothetically you could do a full build of your code without the caching of the OCaml compiler that took 2.5 hours.
  GitLab would fail your full build with time limit failures. But by splitting job A from job B, job A takes 1-1.5 hours
  while job B would only take 1.5 hours plus a few minutes for reading the cache of job A. Now both job A and job B
  can work without running into time limits.

  Why is it a minor break?

  Since there was no announcement of the previous 1.0.0 version, it is unlikely anyone is broken. And if
  anyone is broken, they just need to add three extends: .setup_dkml_XXX to their script.

Other changes:

• Performance: Linux CI now avoids ~10 second ManyLinux (dockcross) unnecessary recursive chown of root:root
  owned container files. As long as calling user is root (which is true for GitHub Actions and GitLab CI/CD)
  the chown operation is skipped.
• Remove unused gl_tags matrix variable
