This commit properly implements the ISBERD (Internal Stage Buffer Entry Read)
instruction that was previously stubbed. The implementation supports all
modes and shift types:
- Patch mode: Reads tessellation patch attributes using ir.GetPatch()
- Prim mode: Reads primitive attributes for geometry shaders
- Attr mode: Reads generic vertex attributes
- Default mode: Maintains backward compatibility
The implementation also supports:
- U16 and B32 shift modes for different data formats
- SKEW and O flags for advanced buffer addressing
- Proper data type conversions and bit casting
This fixes rendering issues in UE4 titles that rely on internal stage
buffer operations in tessellation and geometry shaders. The previous
stubbed implementation caused compatibility problems with modern
rendering pipelines.

- Replace stubbed ISBERD implementation with proper internal stage buffer read
- Add support for different modes (Default, Patch, Prim, Attr)
- Implement shift operations (U16, B32) for buffer data processing
- Convert float results from GetAttributeIndexed to unsigned integers
- Handle buffer index from source register for stage buffer access
- Maintain proper error handling for unimplemented features (SKEW, O)
This completes the internal stage buffer entry read functionality for Maxwell shader translation.

Fix multiple compilation errors preventing successful build:
* Add const qualifier to custom fmt formatter functions across codebase
- Updated formatters in logging, shader recompiler, texture cache, and other modules
- Ensures compatibility with newer fmt library versions
* Add missing fmt/ranges.h includes for fmt::join usage
- Fixed fmt::join calls in Vulkan renderer, GDB stub, NFC service, and main window
- Resolves "no member named 'join' in namespace 'fmt'" errors
* Exclude unsupported platforms from Boost.Process usage in debugger
- Extended conditional compilation to avoid Boost.Process where unavailable
* Fix type casting issues in AOC service manager
- Resolved std::min type mismatch with explicit casting
The frontend IR opcodes do not distinguish between signed and unsigned integer types.
Fixes broken shaders when IR validation/graphics debugging is enabled for shaders that used BitCastS32F32
[REUSE] is a specification that aims at making file copyright
information consistent, so that it can be both human and machine
readable. It basically requires that all files have a header containing
copyright and licensing information. When this isn't possible, like
when dealing with binary assets, generated files or embedded third-party
dependencies, it is permitted to insert copyright information in the
`.reuse/dep5` file.
Oh, and it also requires that all the licenses used in the project are
present in the `LICENSES` folder, that's why the diff is so huge.
This can be done automatically with `reuse download --all`.
The `reuse` tool also contains a handy subcommand that analyzes the
project and tells whether or not the project is (still) compliant,
`reuse lint`.
Following REUSE has a few advantages over the current approach:
- Copyright information is easy to access for users / downstream
- Files like `dist/license.md` do not need to exist anymore, as
`.reuse/dep5` is used instead
- `reuse lint` makes it easy to ensure that copyright information of
files like binary assets / images is always accurate and up to date
To add copyright information of files that didn't have it I looked up
who committed what and when, for each file. As yuzu contributors do not
have to sign a CLA or similar I couldn't assume that copyright ownership
was of the "yuzu Emulator Project", so I used the name and/or email of
the commit author instead.

This seems to be unsupported in newer libstdc++ versions due to
Flow::Block's base class being a non-literal type. It's not clear to me
why this was permitted in earlier versions.
Ensures that we're using the fmt version of format_to.
These are also the only three outliers. All of the other formatters we
have are properly qualified.
