Various methods relating to resource management were previously marked
as kernel-specific, forcing them to stay downstream in the vendor
overlay and eventually be duplicated for DRM code. This patch adds back
this code in kernel-neutral space, allowing for code sharing and
minimising the diff to downstream.

Most Midgard instructions take two-arguments logically; there are always
two arguments at the assembly level. For the few instructions that take
only a single argument, generally the second argument slot is unused,
with a zero inline constant occupying the space. fmov/imov are the
exception, where the first argument is filled with r24 and the logical
argument is in the second slot.
Previously, these constraints were handled by a delicate, buggy series
of hacks. This commit removes these hacks. Instead, we look at the
logical number of arguments (from NIR), switching between two argument
and one-argument-one-zero style. We then introduce a quirk for the
flipped style, which applies to fmov/imov.

The sampler will be ignored since the underlying 'ld_mcs' operation
won't use it, so just fill the field with 0 instead of the texture to
make it clearer that's the case.
This will also avoid is_high_sampler() to kick in unnecessarily, in
case we are using the operation for a texture with index >= 16.

A single shader in Unigine Superposition is affected by this change.
A single iadd is moved to the end of a loop. This iadd is involved in
a complex set of logic to terminate the loop, and an extra mov
instruction is inserted. This shader really needs the optimization
suggested by bugzilla #94747, and I expect that to make this tiny
regression go away.
All Gen7+ platforms had similar results. (Skylake shown)

There are a number of reasons for the rewrite.
1. Adding support for packing tess patch varyings in a sane way.
2. Making use of qsort allowing the code to be much easier to
follow.
3. Fixes a bug where different interp types caused component
packing to be skipped for all varyings in some scenarios.
4. Allows us to add a crude live range analysis for deciding
which components should be packed together. This support can
optionally be added in a future patch.

Regardless of whether the build uses kmsro, kmsro is the default driver
descriptor when the static loader is used. Thus, in an edge case where
the static loader is used, no static targets are loaded, and kmsro is
not compiled, a spurious warning is printed. There's no harm in
executing the stub function in this case, but it's not "an error" to not
have kmsro in the build; the driver missing warning should not printed
kmsro.

In addition to the DRM interface in active development, for legacy
kernels Panfrost has a small, optional, out-of-tree glue repository. For
various reasons, this legacy code should not be included in Mesa proper,
but this commit allows it to coexist peacefully with upstream Panfrost.
If the nondrm repo is cloned/symlinked to the directory
`src/gallium/drivers/panfrost/nondrm`, legacy functionality will be
built. Otherwise, the driver will build normally, though a runtime error
message will be printed if a legacy kernel is detected.
This workaround is icky, but it allows a nearly-upstream Panfrost to
work on real hardware, today. Ideally, this patch will be reverted when
the Panfrost kernel module is mature and we drop legacy support.

The strategy is to keep a CPU-side counter of the direct invocations,
and a GPU-side counter of the indirect invocations, and then add them
together for queries.
The specific technique is a macro which multiplies a list of integers
together and accumulates the product into SCRATCH registers held inside
of the context. Another macro will read those values out and add them to
the passed-in cpu-side counter to be stored in a query buffer the same
way that all the other statistics are stored.
Original implementation by Rhys Perry, redone by Ilia Mirkin to use the
SCRATCH temporaries.
