Build without Win32.mak, and using Universal C Runtime (UCRT)
windows: Check for APPVER, not VCVER for UCRT
When deciding whether UCRT is used (and thus no CRT merge modules), check for
Windows 10 rather than the version of Visual Studio, as we may be building with
an older SDK.

First, bison (and probably flex and other pkgs) got published to the
chocolatey pacman repos compressed using ZST, which requires installing
zstd and broke our Appveyor builds.
Then someone published zstd compressed using ZST, which further broke
our Appveyor build by creating an irrecoverable chicken-egg situation:
pacman can't install zstd because it indirectly depends on zstd.
Possible fixes include trying to install the last version of zstd that
did not have this problem (zstd-1.4.4-2, ascertained from inspecting the
Appveyor build history).
This commit simply stops adding pacman-mirrors, and stops refreshing the
database, and this does get the Appveyor build going again.
Some pacman packages are now being compressed with the ZST algorithm,
but pacman can't handle that unless we first install `zstd`. This
commit does that.
