Check presence of WGL_EXT_colorspace before use

This CL fixes an issue where the WGL_COLORSPACE_EXT_attribute
pixel format query was used without checking the implementation
supports the WGL_EXT_colorspace extension.

Affects:

cts-runner initialization on WGL
glcts.exe initialization on WGL

Components: OpenGL

VK-GL-CTS issue: 2257

Change-Id: Ib4177b851c856570c4b125d537ffa476a02c04f3
