[PATCH 12/15] dxgi: Improve the d3d12_swapchain_CheckColorSpaceSupport() stub.

[Henri Verbeet]

From: Philip Rebohle <philip.rebohle(a)tu-dortmund.de>

Monster Hunter World needs this function to succeed. This
behaves correctly under the assumption that the system has
no HDR support, and only reports standard sRGB as supported.
