appveyor: make VS2010 job build-only, enable Schannel, fix compiler warnings

Tests were consistently flaky for a while.

Also fix compiler warnings in `CertOpenStore()` calls for old MSVC compilers:
```
C:/projects/curl/lib/vtls/schannel.c(688):
  warning C4306: 'type cast' : conversion from 'int' to 'LPCSTR' of greater size
C:/projects/curl/lib/vtls/schannel_verify.c(642):
  warning C4306: 'type cast' : conversion from 'int' to 'LPCSTR' of greater size
```
Ref: https://ci.appveyor.com/project/curlorg/curl/builds/49580310/job/ywu2y44kymgc0nif#L106

Closes #13330
