r300g: allow separate depth and stencil clear

The handling of the CAP is broken in st/mesa anyway. Let's just kill it.

This commit pretty much enables fast Z clear for FBOs with Z24S8.
The driver falls back to clearing with a quad if the fast clear cannot be
used. It can still do fast color clear, for example.
