lib/rendercopy: Add fp16 support for gen4+
Allow copying between fp16 surfaces. We'll use the FLOAT
surface format since that's all the display supports currently.
Hopefully the hardware gives us a 1:1 copy, at least if
the input doesn't contain crazy infs/nans etc. We could
choose UNORM instead but that won't work for eventually
exposing fp16+ccs. Although we do need to replace the
simple bpp value with a more specific format type to get
10bpc+ccs working as well.
