Prevent creation of gpu channels with no GPU on x86-64 windows
https://codereview.chromium.org/1575293002 allowed GPU contexts to be created even when the browser can't use the GPU (for use with swiftshader). However, this seems to be causing renderer hangs on x86-64 windows, so disable it there. Swiftshader currently doesn't work on x86-64 anyway, so it won't affect functionality.
