Fix LTO linking issues on CachyOS with GCC 15.x
- Add LTO support to all core library targets (input_common, frontend_common,
network, shader_recompiler, web_service) that were missing LTO configuration
- Create citron_configure_lto() helper function for consistent LTO handling
- Implement CachyOS-specific detection via /etc/os-release and kernel version
- Apply conservative LTO flags (-flto=auto -ffat-lto-objects) only for
CachyOS + GCC 15+ to resolve linking errors with newer toolchains
- Other distributions continue using aggressive LTO settings for maximum performance
- Disable LTO on executable targets to prevent main function optimization issues
This resolves "undefined symbol" errors when building with -DCITRON_ENABLE_LTO=ON
on CachyOS while maintaining optimal LTO performance on other distributions.
Fixes linking errors including:
- Core::Frontend::EmuWindow symbols
- Core::System methods
- Settings::values
- Common logging functions
Tested on CachyOS with GCC 15.1.1 + LLD 20.1.8

[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.
