One of the reasons we didn't notice that R24_UNORM_X8_TYPELESS
destinations were broken was that an earlier layer was swapping it
out for B8G8R8A8_UNORM. That made Z24X8 -> Z24X8 blits work.
However, R32_FLOAT -> R24_UNORM_X8_TYPELESS was still totally broken.
The old code only considered one format at a time, without thinking
that format conversion may need to occur.
This patch moves the translation out to a place where it can consider
both formats. If both are Z24X8, we continue using B8G8R8A8_UNORM to
avoid having to do shader math workarounds. If we have a Z24X8
destination, but a non-matching source, we use our shader hacks to
actually render to it properly.
