[FFmpeg-devel] [PATCH 1/2] configure: Check for GetStdHandle in addition to SetConsoleTextAttribute

SetConsoleTextAttribute used to be unavailable for Windows Store apps,
but is available to them now. But GetStdHandle still is unavailable,
thus make sure to check for both functions before using code that
requires both.
---
Alternatively we could check for just GetStdHandle instead of
SetConsoleTextAttribute.
