mesa/st: Tie depth clamp lowering in to the VP code

v1: implemented by Erik Faye-Lund <[email protected]>
v2: Add handling of the ARB_clip_control depth mode
v3: Move depth_range_state to file scope and remove training zeros (Erik)
v4: - don't use the one_shader_variant property, as this is not correct (Marek)
    - also use tests on available shader stages to enable depth_clamp lowering
V5: Don't use key.st, use st directly (Marek)
