Build wheels for windows with LuaJit

[emcek]

1. Add Developer Command Prompt for Microsoft Visual C++.

This enables compile all needed libraries and successfully build wheels for both win_amd64 and win32 targets.

2. Add test-command for windows to verify if module luajit21 was included in wheel

3. restrict setuptools<72.0.0 due to test command has been removed, see more details:

• Bite code - setuptools breaks packages
• Remove test command and tests_require pypa/setuptools#931
• [BUG] Many packages are no longer installable after test command is removed pypa/setuptools#4519
• [FR] More gradual breakage of setuptools.command.test pypa/setuptools#4520

4. remove setuptools from Install dependencies step (for MacOS).

It was causing problems during building, when requirements.txt has setuptools with version restriction.

5. Python 3.6 and 3.7 is not supported in Visual Studio 2019 image for AppVeyor

See: https://www.appveyor.com/docs/windows-images-software/#python

It looks to me appveyor is kind of redundant (and slow), but I leave decision to you what to do with it.

Changes are working in my fork and producing working wheels:

• emcek/lupa: Continuous Integration job
• emcek/lupa: Wheel build job

Thanks for digging through the failures here!

Yeah, setuptools!=72.0.0 I've tried this and it doesn't work. Do not remember, but I think I try setuptools==72.1.0 as well and it didn't work.

@scoder Looks like AppVeyor job is passing but doctest of README.rst not! Not sure it is related to newest setuptools since we block only 72.0.0, but with setuptools<72.0.0 it was working at 3dd2562

From logs, there is problem with importing lua54 but job is passing.
