D3D: Fix RGB5_A1 texture upload from PBO failure on Windows 10

Failure is consistently seen in the dEQP tests on Windows 10 on NVIDIA and Intel drivers, where creating an SRV from the buffer in the right format fails. Disable the fast copy path for this format similarly to how it's already disabled for some other formats.
