gallium: add CAPs for indirect addressing and lower it in st/mesa when needed

Required because ATI and NVIDIA DX9 GPUs do not support indirect addressing
of temps, inputs, outputs, and consts (FS-only) or the hw support is so
limited that we cannot use it.

This should make r300g and possibly nvfx more feature complete.
