mesa/st: add tgsi-lowering code for depth-clamp

This is a TGSI pass that lowers depth-clamping into shader-operations,
by replacing the depth-value with 0 (a z-coordinate of zero will always
pass the OpenGL depth test conditions), and using a dedicated varying to
interpolate the real depth-value instead. Finally we replace the
depth-output in the fragment shader.

Optimizations that insert bitshift or bitwise operations should not be

The .lower_bitshift could be used to control the bitshift related ones,
but there was also one bitwise optimization uncovered.
Since only lima and freedreno use this option and the use case is that
no bit operations are wanted, let's rename it to .lower_bitops and use
it to control all bitops related optimizations.
