This provides bit and common code to control autostrip state.
Requirement for this is coming from Wa_14026781792. We are writing
register for Wa_14024997852 and since this register is nonmaskable
the bit needs to be written always. Helper takes care to touch only
required bits.

This optimization doesn't work when the ray query index isn't uniform across
the subgroup, which is something the spec allows. While there are some smart
ways to fix this and still avoid unnecessary spilling, its not worth investing
the time until we find a realtime raytracing workload that actually needs to
use multiple live ray queries for something.

Allows a shader to have multiple ray queries without spilling them to a shadow

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
done && \
sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

Add a `--bits-format` argument to normalize the output to either of the
formats described below. For now, defaults to the old format.
The documentation in PRMs and BSpec describe the fields with the dword
and the bit range. Using the same convention makes easier to spot
issues.
Old format:
```
<field name="Disable SLM Read Merge Optimization" start="38" end="38" type="bool" />
<field name="Pixel Async Compute Thread Limit" start="39" end="41" type="uint" prefix="PACTL">
```
New format:
```
<field name="Disable SLM Read Merge Optimization" dword="1" bits="6:6" type="bool" />
<field name="Pixel Async Compute Thread Limit" dword="1" bits="9:7" type="uint" prefix="PACTL">
```
For Groups, we store the dword and if needed a offset_bits, in case
a group starts in a non-aligned position. Size and count for groups are
not changed.
Do this first for gen_sort_tags.py in case is convenient to have for the
stable tree to convert future patches from the new back into the old
format. Later patches will add support to the rest of the code.
