Aaron Carlisle 9f044cb422 Remove MinGW support
The Issue
=======

For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.


Why Remove
==========

One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work.  For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch

If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.

For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3

Fixes T51301
