appveyor: Increase build coverage to all VS solutions

Using the 'for' construct allows the specification of a more complex
build matrix. This additionally simplifies the builds using MinGW and
Cygwin because the build script can be unified and does not require
checking for the 'Release' configuration.

This change also extends the MinGW builds to cover both 32-bit and
64-bit builds using GCC versions 6.3.0 and 8.1.0, respectively. The
Cygwin builds were similarly extended to include 64-bit build coverage.
