nvfx: support using blitter to copy depth/stencil resources, fix Heaven
We might want to copy them as color ones though.
Also works around crash in Unigine Heaven due to failing to allocate
a 64 MB temporary in GART for a CPU copy.
Unigine Heaven now works on nv40, albeit with very heavy glitches (with
the floating branch with render_hdr 0).
