r300: Writing to result.depth in fragment programs (R3xx; only stub for R5xx)

Setup fg_depth_src for depth writing programs and change early Z (ztop)
semantics.

Piglit's version of glean/fragprog test passes now (unlike Glean, its
dependency on EXT_fog_coord, which we don't support, is optional).

R3xx only at the moment, but should be straightforward to adapt to R5xx
(I don't own an R5xx, and I don't want to break anything.)
