lima/ppir: refactor texture code to simplify scheduler

The 'varying fetch' pp instruction deals only with coordinates, and
'texture fetch' deals only with the sampler index.
Previously it was not possible to clearly map ppir_op_load_coords and
ppir_op_load_texture to pp instructions as the source coordinates were
kept in the ppir_op_load_texture node, making this harder to maintain.
The refactor is made with the attempt to clearly map ppir_op_load_coords
to the 'varying fetch' and ppir_op_load_texture to the 'texture fetch'.
The coordinates are still temporarily kept in the ppir_op_load_texture
node as nir has both sampler and coordinates in a single instruction and
it is only possible to output one ppir node during emit. But now after
lowering, the sources are transferred to the (always) created
ppir_op_load_coords node, and it should be possible to directly map them
to their pp instructions from there onwards.

lima/ppir: lower texture projection

Lower texture projection in ppir using nir_lower_tex and nir_lower_tex.
This will insert a mul with the coordinate division before the load
varying.

Even though the lima pp supports projection in the load varying
instruction while loading the coordinates (from a register or a
varying), it requires that both the coordinates and projector be
components in a single register.
nir currently handles them in separate ssa, and attempting to merge them
manually may end up in worse code than just doing the coordinate
division manually. So for now let's just lower the projection to add
support for it in lima.
In the future, an optimization pass may be implemented in lima to ensure
that both coords and projector come in the same register, then this
lowering may be disabled and in this case lima may use the built-in
projection and save the mul instruction from lowering.

iris: Skip repeated depth buffer disables.

Often times, the depth buffer is entirely disabled, but color render
targets change.  For example, GenerateMipmaps will change the color
render target for each miplevel, but there is no depth buffer.

In the Civilization VI benchmark, this drops the median number of
