Move the duplicate consts step to a nir pass.
This makes the nir representation closer to what ppir will have in the
result.
Additionally, it handles the case where a const is used multiple times
by a single node (which can happen in instructions like fcsel). The new
implementation will only emit a single load const for that case.

Move the duplicate uniform and varying steps to a nir pass, along with
some changes in the duplicating strategy.
Node duplication is now done per user of the varying/uniform. This is
inspired by what the offline shader compiler seems to usually do, and as
usual aims to reduce register pressure and better utilize the ld_uni and
ld_var instruction slots.
It is worth noting that due to a bug/feature, ppir was already
duplicating uniforms per successor in ppir_node_add_src even if the
comment indicated it was meant to be per-block.
Additionally, ppir was duplicating load uniform nodes twice for nodes
that use the same uniform in more than one source, resulting in one
unnecessary (and unpipelineable) load. This new implementation in nir
only creates one load in that case.

This makes the streams more readable and comparable with the blob's parser
as it parses the VS and PLBU stream and shows the currently known values.

NIR may emit a single instrinsic to load several packed varyings,
but that's suboptimal for Utgard PP for several reasons:
- varyings that are used as sampler inputs can be passed using
pipeline register with increased precision
- we have small number of regs, so using a vec4 regs for storing
two vec2 varyings increases reg pressure.
Add NIR pass to split a single load into several loads and utilize
it in lima.

Add better liveness analysis that was modelled after one in vc4.
It uses live ranges and is aware of multiple blocks which is prerequisite
for adding CF support

This will allow both drivers to share this code. Both drivers
build-tested with meson. Android build not tested.
v2: Change naming from tiling->shared, in case Lima and Panfrost can
share more in the future. Fix Android build system.
