pan/bi: Push UBOs on Bifrost
Based on the Midgard pass. Results look better since Midgard already had
a basic UBO pushing pass to begin with. Particularly nice to see the
dramatic reduction in spilling.

pan/bi: Rework FAU lowering
Move and reshape bi_lower_fau to bi_schedule.c. This generalizes the
pass for FAU reads, allowing copyprop to work with FAU without problems.
The pass must run immediately before scheduling. Its post-conditions are
directly specified as the scheduler's pre-conditions. It momentarily
will depend on internal scheduler predicates. It is, for all intents and
purposes, part of the scheduler. Keep it all together.
Finally, adjust the 0 handling to avoid a move at the expense of
constrained scheduling of something like `FADD.v2f16.clamp_0_1 u0, #0`

panfrost: Fix race condition in UBO mapping to CPU
In theory, a compute shader (or transform feedback) could write to an
SSBO, rebind as a UBO, and then read as a UBO later in the same frame.
We would need to flush in this case so we don't push stale data to the
later shader. This seems sufficiently obscure, but if this is a
performance issue in a real workload, we could emit a small compute
shader to do the copies without flushing.

pan/mdg: Optimize UBO offset calculations
LD_UNIFORM supports constant shifts and biases, just like LD, so take
advantage of that. Will avoid a regression in code quality from lowering
uniforms to UBOs.
No shader-db changes.

pan/mdg: Add MIDGARD_MESA_DEBUG=inorder option
Helpful to disable the scheduler when debugging, so the assembly can be
compared against the NIR directly when lost in a big dEQP test.
