intel/vec4: Set brw_stage_prog_data::has_ubo_pull

In 0e4a75f917, Ken added a flag brw_stage_prog_data which indicates
whether any UBO pulls ever occur.  Unfortunately, he neglected to set
the bit in the vec4 back-end.  This was fine at the time because the
optimization was intended for iris which does not support gen7 and using
the vec4 back-end on Gen8+ requires an environment variable.  We want to
use this in Vulkan which does support Gen7 so we want the information
from the vec4 back-end as well as scalar.

st/mesa: lower global vars to local after lowering clip

When this code was merged, this wasn't necessary because the
state-tracker would do it later anyway. But this recently got changed,
without changing the code that depended on this.

Arguably, this was a mistake in the lowering pass to begin with. Either
way, let's fix it by not assuming that the lowering code gets called
later when it's not needed.

This fixed user-defined clip-planes in Zink.

zink: emulate optional depth-formats

The Vulkan spec says that an implementation has to support one of
VK_FORMAT_X8_D24_UNORM_PACK32 and VK_FORMAT_D32_SFLOAT, as well of
one of VK_FORMAT_D24_UNORM_S8_UINT and VK_FORMAT_D32_SFLOAT_S8_UINT.

So let's keep track which one is supported of earch pair, and emulate
one on top of the other one.

This won't give the exact result for comparisons, or when mapping and
unmapping the resources. But it's better than flat out failing to create
the resource, and we can fix the map/unmap issue later if needed.
