i965/fs: Remove brw_wm_compile::computes_depth field.
Everybody determines this by checking if fp's OutputsWritten field contains the FRAG_RESULT_DEPTH bit. Rather than having payload setup check this and set the computes_depth flag, we can just do the check in the only place that actually used it: emit_fb_writes().
