Message : Re-land "D3D11: Fix readback of BGRA-backed formats." For some BGRA-backed formats (RGBA4, R5G6B5, RGB5A1), our ReadPixels implementation wasn't aware the BGRA format didn't exactly match the RGBA format. For these it would do the 'fast path' memcpy method, when it should stop and do the slow pixel-by-pixel packing method. Fixes conformance2/reading/read-pixels-from-fbo-test.html. Reland: fix empty format info that was causing us to only see the first pixel in the FBO in a ReadPixels call. Also fix bugs in the unorm 16-bit format readback code, and add ASSERTs to catch bugs in subsequent new formats.
