inspector/general.c: Check whether GL context supports WGL

Browse Source 
We may well be using an EGL context that does not support Desktop (W)GL on
Windows, such as in the case of using libANGLE.  So, check whether WGL is
supported for this running instance before trying to query WGL extensions.

This will get rid of warning messages from libepoxy.
