ConfigTest - Virtual display python unit test

[meimchu]

ConfigTest: Python unit test updated with additional virtual display unit tests. Accompanying features introduced in #1464

Follow up questions and comments:

• I would like to ask for some guidance on the cpp part of the unit tests which deal with the different OS platforms. What would be the right way to implement that logic in the python side? Thanks!
• I have left the test_virtual_display() method alone for now. Let me know if you think my new ConfigVirtualDisplayTest provides sufficient coverage so that can be removed.
• I mainly followed closely to the virtual display-related unit tests I saw in the cpp unit tests per suggestion. There are some still more "traditional" testings that I can add to it later as well.

Good job.
There is few minor code improvements but the core is here.

Concerning the platform specific tests I suggest to forget them for short-term because it requires to find out the platform (possible with Python) but also having the headless mode i.e. OCIO_HEADLESS_ENABLED. The latter is currently not available for Python unit tests.
That could be a 'follow-up' branch.

(Re-launched the Wheel jobs, there was an issue with Chocolatey failing to install the doxygen package. I already saw that a few time and have no real idea on where it comes from but most likely an issue on their side.)
